What is the chemical formula for antimony V?
The chemical formula for antimony V is Sb2O5. It is often referred to as antimony pentoxide.
What ion has 46 electrons and 50 protons?
If an ion has 46 electrons and a 5+ charge, then it has 51 protons. It is an antimony ion (Sb5+)
What type of bond do antimony normally form?
Anntimony is a metalloid. It does not form salts with Sb3+ or Sb5+. It can form Sb3- (similar to P3-) it can also form more complex anions such as Sb73- Antimony is more often encountered covalently bonded.
What is the average IQ score for a 16 year old?
The average IQ for all people at all ages is a standard score of 100. The average range for some tests (such as the KABC-2) includes standard scores from 85 - 115. For some tests (such as the WISC-IV, WPPSI-III, WAIS, WNV, SB5) is 90 - 109. Either way, 100 is dead average.
What is the average IQ for an adult female 50 and over?
The average IQ for all people at all ages is a standard score of 100. The average range for some tests (such as the KABC-2) includes standard scores from 85 - 115. For some tests (such as the WISC-IV, WPPSI-III, WAIS, WNV, SB5) is 90 - 109. Either way, 100 is dead average.

What is the IQ score when your percentile is 90?
The most reputable and widely used IQ tests used at present -- the individual (psychologist- or psychometrist-administered) WISC, WAIS, SB4 and SB5 -- are designed to have population average IQs of 100, with a standard deviation of 15. On such tests, the 90th percentile IQ is 119. On older individual and some group tests, the 90th percentile IQ may differ (usually, it is a bit higher -- 120 or 121). IQ scores and percentiles obtained from most online tests are not comparable to the individual IQ test results quoted here and should not be relied upon in clinical, employment-related, or educational situations. By the way, the IQ coinciding with 1 standard deviation above the mean is 115. An IQ of 115 is at the 84th percentile on the standard individual tests, and so must be considered a moderately high score. The 90% percentile score of 119 is at the lower limit of what might be considered a high, or clearly above average, IQ score. An IQ of 132 (98th percentile) or higher is required to join Mensa.

How many states have standardized testing?
Ability/ Achievement testsAbility/ Achievement tests are used to evaluate a student's or worker's understanding, comprehension, knowledge and/or capability in a particular area. They are used in academics, professionsand many other areas.A general distinction is usually made between tests of ability/ aptitude (intelligence tests) versus tests of achievement (academic proficiency).[edit]IQ testsStanford-Binet Intelligence Scales (SB5)Wechsler Adult Intelligence Scale (WAIS)Wechsler Intelligence Scale for Children (WISC)Wechsler Preschool and Primary Scale of Intelligence (WPPSI)Otis-Lennon School Ability TestDifferential Ability Scales (DAS)Woodcock-Johnson Tests of Cognitive Abilities (WJ)[edit]Achievement testsWechsler Individual Achievement Test (WIAT)Kaufman Test of Educational Achievement (KTEA)Woodcock-Johnson Tests of Achievement (WJ)[edit]Public schoolsMain article: List of state achievement tests in the United StatesNational Assessment of Educational Progress (NAEP)State achievement tests are standardized tests required in American public schools for the schools to receive federal funding.

What do codes in the paralympics mean?
Disability categories- Amputee: Athletes with a partial or total loss of at least one limb.- Cerebral Palsy: Athletes with non-progressive brain damage, like cerebral palsy, traumatic brain injury, stroke or similar disabilities affecting muscle control, balance or coordination.- Intellectual Disability: Athletes with a significant impairment in intellectual functioning and associated limitations in adaptive behavior. (This category is currently suspended.)- Wheelchair: Athletes with spinal cord injuries and other disabilities which require them to compete in a wheelchair.- Visually Impaired: Athletes with vision impairment ranging from partial vision, sufficient to be judged legally blind, to total blindness.- Les Autres: Athletes with a physical disability that does not fall strictly under one of the other five categories, such as dwarfism, multiple sclerosis or congenital deformities of the limbs such as that caused by thalidomide. (The name for this category is the French for "the others").http://en.wikipedia.org/wiki/ParalympicsInternational Blind Sports Association (IBSA) ClassesB1 -- An athlete in this class will either have no light perception at all in either eye or may have some light perception but an inability to recognize the shape of a hand at any distance or in any direction.B2 -- The athlete can recognize the shape of a hand and has the ability to perceive clearly up to *2/60. The visual field of the athlete is less than five degrees.*2/60: A person can see at two meters what is normally seen at 60 meters. B3 The athlete can recognize the shape of a hand and the ability to perceive clearly above 2/60 up to 6/60. The visual field of the athlete varies between more than 5 degrees and less than 20 degrees.Cerebral Palsy International Sport and Recreation Association (CP-ISRA)CP1, CP2, CP3, and CP4 are classes of athletes with cerebral palsy who use a wheelchair during competition (excluding swimming).CP5, CP6, CP7, and CP8 are athletes with cerebral palsy who do not use a wheelchair during competition.CP1 -- Athletes with poor functional range of movement and poor functional strength in arms, legs, and trunk. The athletes use electric wheelchairs or assistance for mobility. They are unable to propel a wheelchair. The athletes compete in a wheelchair.CP2 -- Athletes with poor functional strength in arms, legs, and trunk. The athletes are able to propel a wheelchair. The athletes compete in a wheelchair.CP3 -- The athletes show fair amount of trunk movement when pushing a wheelchair, but forward trunk movement is often limited during forceful pushing. Although showing some trunk movement while throwing, motions are mostly from the arm. The athletes compete in a wheelchair.CP4 -- The athletes show good functional strength with minimal limitations or control problems in arms and trunk. The athletes show poor balance. The athletes compete in wheelchairs.CP5 -- The athletes have normal static balance, but show problems in dynamic balance. A slight shift of center of gravity may lead to loss of balance. The athletes may need an assistance device for walking, but not necessarily when standing or throwing (in athletics field events). The athletes may have sufficient function to run on the track.CP6 -- The athletes do not have the capability to remain still: They show involuntary cyclic movements and usually all four limbs are affected. The athletes are able to walk without any assistance. They usually have more control problems with the arms and they have better leg functions than CP5, especially when running.CP7 -- The athletes have uncontrollable muscular spasms in one half of the body. They have good functional abilities in the dominant side of the body. They walk without assistance but often with a limp due to uncontrollable muscular spasms in the leg. While running, the limp may disappear almost totally. Their dominant side has better development and good follow-through movement in walking and running. Arm and hand control is affected only on the nondominant side; good functional control is shown on the dominant side.CP8 -- The athletes show a minimum of uncontrollable spasm in either one arm, one leg, or one half of the body. To be eligible, these athletes need to have a diagnosis of cerebral palsy or other nonprogressive brain damage.International Sports Federation for Persons with Intellectual Disability (INAS-FID)To become eligible to compete in the Paralympic Games, all athletes with an intellectual disability have to reach the minimum disability criteria, which, in accordance with the World Health Organization (WHO) definition, are determined by:An IQ score below 70. (The IQ score of the average person is 100.)Limitations in regular skills areas (communication, self-care, social skills, etc.).Onset before the age of 18.Following is a list of the 18 medal sports with their classifications and a brief explanation of the physical function of each class. The classifications reflect the functional ability a particular athlete is expected to have. (Wheelchair basketball and intellectual disability basketball together are one medal sport; similarly, sitting volleyball and standing volleyball.)ArcheryThe archery classification system is divided into three different classes:Archery Standing = ARST Archery Wheelchair 1 = ARW1 Archery Wheelchair 2 = ARW2ARST -- Archers in the standing class have no disabilities in the arms. The legs show some degree of loss of muscle strength, coordination and/or joint mobility.ARW1 -- Archers in the ARW1 class have disabilities in arms and legs. They have limitations in range of movement, strength and control of arms, and poor or nonexisting control of the trunk. The legs are considered nonfunctional due to amputations and/or similar limitations of movement, strength and control. They compete in a wheelchair.ARW2 -- Archers in the ARW2 class have paralysis in the lower part of the body, including the legs. They compete in a wheelchair.Athletics (Track and Field)In athletics, competitors from all six disability categories compete: visually impaired; intellectually disabled; cerebral palsy; amputees; les autres; and spinal cord injury athletes competing in wheelchairs.Therefore, the class nomenclature is structured accordingly:Classes 11-13 cover the different levels of vision impairment.Class 20 covers intellectually disabled athletes.Classes 32-38 cover the different levels of cerebral palsy.Classes 42-46 cover the different levels of amputations and other disabilities (les autres).Classes 51-58 cover the different levels of spinal chord injuries.The letter "T" marks track events; the letter "F" stands for field events. The lower the class number, the higher the level of disability; the higher the class number, the lower the level of disability.Track ClassesT11 -- B1 athletes.T12 -- B2 athletes.T13 -- B3 athletes.T20 -- Athletes with an intellectual disability.T32 -- CP2 athletes. There are no events in class T32. The athletes compete together with athletes in class T33.T33 -- CP3 athletes. T32 athletes (CP2) compete in this class.T34 -- CP4 athletes.T35 -- CP5 athletes.T36 -- CP6 athletes.T37 -- CP7 athletes.T38 -- CP8 athletes.T42 -- Single above-knee amputation or combined arm/leg amputations.T43 -- Double below-knee amputation or combined arm/leg amputations.T44 -- Single below-knee amputation or athletes who can walk with moderately reduced function in one or both legs.T45 -- Double above-elbow amputations or double below-elbow amputations.T46 -- Single above-elbow amputation, single below-elbow amputation, or athletes who have normal function in both legs but impairment in the trunk and/or arms.T51 -- Mild weakness in shoulders.

It may also include athletes with severe problems when walking, such as impairments in one leg from polio.F43 -- Double below-knee amputations or athletes with combined leg/arm amputations. Athletes may also have normal function in the throwing arm in association with reduced function in the legs or certain balance problems.F44 -- Single below-knee amputation. Athletes with normal function in the throwing arm and slightly reduced function in the legs or slight balance problems.F45 -- Double above-elbow amputations and double below-elbow amputations.F46 -- Single above-elbow amputation and single below-elbow amputation.

Have an increase in leg function in comparison with F56.F58 -- Have normal arm and hand function. Have normal trunk function. Have more leg function than F57.Basketball - WheelchairTo be eligible to play wheelchair basketball an athlete must have a permanent physical disability in the lower limbs that prevents him or her from running, jumping, and pivoting as an able-bodied player.Once a player has met this requirement, he or she is classified to play under the International Wheelchair Basketball Federation's (IWBF) Player Classification System.Players are assigned a point value from 1.0 through to 4.5 according to their level of physical function. These points are then added together with a team not permitted to exceed 14 points for the five players on court at any given time. This ensures that any player, regardless of degree of disability, has an integral role to play within the team structure.Observed trunk movements and stability during actual basketball competition, not medical diagnosis, form the basis of player classification.1 point players -- Have no lower limb movement, and little or no controlled trunk movement. Their balance in both the forward and sideways directions is significantly impaired, and they rely on their arms to return to the upright position when unbalanced. These players have no stability in a contact situation and usually rebound overhead single-handed.2 point players -- Usually have no lower limb movement, but have some partially-controlled trunk movement in the forward direction. They do not have controlled sideways movement or trunk rotation. Players have limited stability in a contact situation, often relying on their handgrip to remain upright in a collision.3 point players -- May have some lower limb movement. Have controlled trunk movement forward to the floor and up again, and have some rotation control. Players do not have good sideways trunk control, but are more stable in a contact situation and able to comfortably rebound overhead with two hands.4 point players -- Have normal trunk movement, but due to some reduced lower limb function are unable to lean sideways to both sides with full control. Stable in contact and rebounding, with normal forward and rotation movements.4.5 point players -- The players with the least disability on court. Usually have only minimal lower limb dysfunction or single below-knee amputation. Normal trunk movement in all directions. Very stable in contact and rebounding.There are situations where a player does not fit into the exact categories for classification. In these cases, the classifiers may assign a player a half-point above or below a certain class. This creates players with 1.5, 2.5, or 3.5 points assigned to them. The team total of 14 points on court does not alter when this occurs.Basketball - Intellectual DisabilityTo become eligible for basketball intellectual disability, all athletes have to reach the minimum disability criteria laid down by INAS-FID, the world governing body for athletes with an intellectual disability.BocciaBC1 -- CP1 and CP2. Compete with assistance.BC2 -- Only CP2. No assistance permitted.BC3 -- Severe CP1. Compete with some assistance device.CyclingCY -- B1, B2, and B3. The athletes compete together in an open class.LC1 -- The athletes have minor or no leg disabilities and no other disabilities. The class includes athletes with an amputation of more than half-foot (forefoot) or a leg length difference of 7-12cm.LC2 -- The athletes have a disability on one leg, but they are able to pedal normally using both legs (with or without prosthesis). The class includes athletes with single above- or below-knee amputations or a length difference of more than 12cm.LC3 -- The athletes have a disability on at least one leg, and pedal only with the other leg. The class includes athletes with loss of muscle strength in both legs or the limited flexion ability of the knee less than 50 degrees.Division 2 CP5 and CP6 together (tricycle).Division 3 CP5 and CP6 together (bicycle).Division 4 CP7 and CP8 together.EquestrianGrade 1 -- The athletes are mainly wheelchair users with either poor trunk balance or the limitation of function in all arms and legs. Athletes with no trunk balance but good arm functions are also eligible in this class.Grade 2 -- The athletes are mainly wheelchair users or those with severe movement disabilities, involving the trunk balance, but with good to mild arm functions. Athletes with loss of function of both arm and leg on one side of the body are also eligible in this class.Grade 3 -- The athletes are mainly able to walk without support. The may have either disabilities in both arm and leg on one side of the body, moderate disabilities in both arms and both legs, or severe arm disabilities. Athletes classified as B1 are also eligible in this class.Grade 4 -- The athletes have a disability in only one or two extremities or some visual impairment (B2, B3).FencingIn fencing, only athletes in a wheelchair can compete.A CategoryAthletes from Class 3 and 4.Class 3 -- The athletes have a good sitting balance of the trunk without support of the legs (double above-knee amputations). The arm used for fencing is functional.Class 4 -- The athletes have good sitting balance and support of the legs. The arm used for fencing is functional.B CategoryAthletes from Class 2.Class 2 -- The athletes have bad or fair/moderate sitting balance. The athletes with bad sitting balance have no problem with the fencing arm. The athletes with good sitting balance have a minimally affected fencing arm.(Athletes from Class 1 do not compete in the Paralympic Games.)Football (Soccer)Athletes with the classes CP5, CP6, CP7, and CP8 are eligible to compete.One player from classes CP5 and CP6 must be in the field at all times. (If not, the team must play with six players instead of seven.)GoalballAthletes with the class B1, B2, and B3 are eligible to compete.The athletes compete together in an open event. During competition all athletes have their eyes covered.JudoAthletes with the class B1, B2, and B3 are eligible to compete. The athletes compete together in an open event. The same seven weight divisions in Olympic judo competition are in Paralympic judo.PowerliftingIn powerlifting, athletes with amputations and other (les autres) disabilities can compete together with CP athletes, wheelchair athletes, and dwarfs. Competition is divided into different weight classes.To become eligible in international powerlifting competition, the athletes have to meet the minimum disability criteria, as outlined in the relevant publications of ISOD, CP-ISRA, and ISMWSF.Amputees and les autres (ISOD): Amputation through or above ankle of one leg. Slightly reduced function in the legs or slight balance problems.Cerebral palsy (CP-ISRA): Minimal but obvious impairment of functions. Evidence of spasticity and/or involuntary movement in at least one limb.Wheelchair athletes (ISMWSF): Athletes must have at least 10 percent loss of function of their lower limbs.Additionally, the competitor must have the ability to fully extend the arms, with no more than 20-degree loss of full extension in either elbow, to perform an approved lift according to the IPC powerlifting rules.SailingSailing is a multidisability sport, where athletes from the following disability groups can compete together:Amputees / les autres athletesSpinal cord injuries athletesCerebral palsy athletesVisually impaired athletesThe classification system is based entirely on the functions required to compete in sailing.Four functional classes have been identified:StabilityHand functionsInabilityVisionIn each functional class the athletes are categorized under one of several categories, depending on their functional limitations, and are finally rated according to a point system, from one point, describing the most limited functional ability, up to seven points, describing the highest level.Each crew of three sailors is allowed a maximum of 12 points.ShootingIn shooting, athletes with a physical disability (amputees and les autres, cerebral palsy or spinal cord injuries) reaching minimum disability criteria can compete.The shooting classification system is divided into two main classes:SH1 -- Pistol and rifle competitors who do not require a shooting stand.SH2 -- Rifle competitors who have no ability to support the weight with their arms and therefore require a shooting stand.SwimmingSwimming is the only sport that combines the conditions of limb loss, cerebral palsy (coordination and movement restrictions), spinal cord injury (weakness or paralysis involving any combination of the limbs), and other disabilities (such as dwarfism or major joint restrictions) across classes.All classes begin with an "S."Classes S1-S10 -- are for swimmers with a physical disability.Classes S11-S13 -- are for swimmers with a visual impairment.Class S14 -- is for swimmers with an intellectual disability.The prefix "S" to the class denotes the class for freestyle, backstroke and butterfly.The prefix "SB" to the class denotes the class for breaststroke.The prefix "SM" to the class denotes the class for individual medley.The range is from the swimmers with severe disability (S1, SB1, SM1) to those with the minimal disability (S10, SB9, SM10).In any one class some swimmers may start with a dive or in the water depending on their condition. This is factored in when classifying the athlete.Below are some examples of swimming functional classes:S1, SB1, SM1 -- Swimmers who have severe coordination problems in four limbs or have no use of their legs, trunk, hands and minimal use of their shoulders.S2, SB1, SM2 -- Similar disabilities to class S1, but these athletes would have more propulsion by using their arms and legs.S3, SB2, SM3 -- Swimmers with reasonable arms strokes but no use of their legs or trunk. Severe limb loss to four limbs. Athletes in this class would have increased ability when compared with S2.S4, SB3, SM4 -- Swimmers who use their arms and have minimal weakness in their hands but have no use of their trunks or legs. Swimmers with coordination problems affecting all limbs but predominantly the legs. Also for severe limb loss to three limbs. Increased ability when compared with S3.S5, SB4, SM5 -- Swimmers with full use of their arms and hands but no trunk or leg muscles. Swimmers who still have coordination problems.S6, SB5, SM6 -- Swimmers with full use of their arms and hands, some trunk control but no useful leg muscles. Swimmers with coordination problems, although usually these athletes can walk. Also for dwarfs and swimmers with major loss in two limbs.S7, SB6, SM7 -- Swimmers with full use of their arms and trunk with some leg function. Swimmers with coordination problems or weakness on the same side of the body. Limb loss in two limbs.S8, SB7, SM8 -- Swimmers with full use of their arms and trunk with some leg function. Swimmers with use of one arm only or some limb loss.S9, SB8, SM9 -- Swimmers with severe weakness in one leg only. Or swimmers with very slight coordination problems or with one limb loss. Usually these swimmers start out of the water.S10, SB9, SM 10 -- Swimmers with minimal weakness affecting the legs. Swimmers with restriction of hip joint movement. Swimmers with some deformity in their feet or minor loss of a part of a limb. This class has the most physical ability.S11, SB11, SM11 -- These swimmers are unable to see at all and are considered totally blind. They must wear blackened goggles in this class and will require someone to tap them when they are approaching the wall. B1 athletes.S12, SB12, SM12 -- These swimmers can recognize shapes and have some ability to see. There is a large range of vision ability within this class. B2 athletes.S13, SB13, SM13 Swimmers who have the most sight but legally are still considered to have a vision impairment problem. B3 athletes.S14, SB14, SM14 -- Swimmers who have a recognized intellectual disability according to the international standards set by the World Health Organization (WHO) and adopted by the governing sports body, INAS-FID.Table TennisThe table tennis classification system comprises 10 functional classification classes for athletes with cerebral palsy, with amputations and other disabilities (les autres), and one class for athletes with intellectual disability.TT1 -- Elbow and hand extension are achieved by a swinging movement initiated from the shoulder. Coordination of arm movement is significantly different from nonimpaired arm.(CP: Severe muscle stiffness in the whole body, reducing speed and precision of arm movement and reducing sitting balance.)TT2 -- Elbow extension is sufficient and hand movements are well coordinated but without normal power.(CP: Same as TT1 with almost-normal playing arm.)TT3 -- Minimal loss of function in playing hand. Slight changes in body position are secured by the free hand propping, holding, or pushing at wheelchair or thigh. Lower part of body keeps in contact with the back of the seat. Backward movements of the arm are reduced because of body balance disorders.(CP: Minimal limitations in control of both arms and severe stiffness in both legs.)TT4 -- Normal arm and body movements. Body movements to increase reach only possible by using free arm to prop, hold or push at wheelchair or thigh. When starting with one hand, forward body cannot lean forward optimally. Double above-knee amputees with short stumps.(CP: Moderate stiffness and reduction of precision of arm and body movements.)TT5 -- Athlete may bend forward and backward without using the nonplaying arm. Significant pushing actions with thighs or feet. Wheelchair handling is optimal because of good body positioning backward and forward. Some sideward movement is possible.(CP: Slight to minimal stiffness or loss of precision in arms and body, and some affection of the legs.)TT6 -- Combination of disabilities in the playing arm and legs.(CP: Moderate stiffness and loss of precision more in legs than in arms, or involuntary movements in the whole body.)TT7 -- Both arms are affected. Single (playing arm) or double above- or below-elbow amputation or combination of both.(CP: Moderate involuntary movements.)TT8 -- Severe disability in one or both legs. Single above-knee or double below- knee amputation.(CP: Some loss of precision and some stiffness in legs and arms.)TT9 -- Good dynamic balance. Minimum disability in one or both arms or differential length in legs. Single below-knee amputation.(CP: Slight loss of precision in one side of the body.)TT10 -- Normal function in playing arm.

In other words, a player must have a permanent substantial or total loss of function in one or two legs.If, as a result of these functional limitations, this person would be unable to play competitive able-bodied tennis (that is, having the mobility to cover the court with adequate speed), then this person would be eligible to play wheelchair tennis in sanctioned International Tennis Federation (ITF) tournaments.Athletes who play in sanctioned ITF tournaments are not required to undergo classification upon arrival at the Sydney 2000 Paralympic Games.Volleyball - SittingAthletes in sitting volleyball only need to reach the criteria for minimum disability as described for class A in volleyball.Sitting volleyball is played by amputees and athletes with other (les autres) disabilities.Each team may have a maximum of one minimum-disability player on the court at any one time; the rest of the team must have a higher level of disability.Volleyball - StandingThe volleyball classification system distinguishes between three classes: A, B, and C.At any time a team may have a maximum of one player from class A and must have a minimum of one player from class C on the court.Class AAn athlete with the minimum disability level related to the skills/functions to perform volleyball.Examples include amputation of fingers, shortening of one arm/one leg to a certain percentage, fusion of ankle or wrist, as well as CP7 and CP8 and other comparable disabilities.Class BAn athlete with a medium level of disability related to the skills/functions required to perform volleyball.
