Strontium is a chemical element with the atomic number 38 and symbol Sr. This alkaline earth metal was used primarily in cathode ray tubes in early televisions.
500 Questions
What is similar to strontium?
Asked by Wiki User
Calcium,barium and radium are mostly similar to strontium by properties, because these elements have the same structure of external electron orbits ( outer-shell orbitals 2s).Because of the similarity of the outer shell orbitals these elements are placed in the same group.
Magnesium and beryllium have also the same structure of outer shell orbitals like strontium(2s)but they are more similar to zinc or aluminium than to strontium.
Why the formulas of barium chloride and strontium chloride are similar?
Asked by Wiki User
It is because Barium and Strontium are both elements of same group and have same outer shell configuration of ns2
where n is the principal quantum number or shell number.
Furthermore, they both are bonded to same element.
Hence, the formula of Barium and Strontium Chloride are similar.
Does rubidium and strontium ion have the same electronic configuration?
Asked by Wiki User
NO!!!!
Each element has it own ground state electron configuration.
Rubidium is [Kr] 5s1
Strontium is [Kr] 5s2.
Notice that strontium has one MORE electron than Rubidium.
The symbol [Kr] is shorthand for the full electron configuration of krypton.
What is the formula for an ionic compound made of strontium and sulfur?
Asked by Wiki User
The formula unit for the ionic compound made of strontium and sulfur is SrS, called strontium sulfide.
What is the Noble-gas configuration for Strontium?
Asked by Wiki User
The bipositive ion of strontium takes the electron configuration of xenon.
Does strontium have the tendency to lose or gain electrons in a chemical reaction?
Asked by Wiki User
You wouldn't expect strontium to gain electrons in a chemical change.
Appearance of strontium at room conditions?
Asked by Wiki User
in my high chemical equipment, in my science lab i have found the correct answer and the highly best answer is gas!
What does strontium bond with?
Asked by Wiki User
this stupid web site doesnt know the answer sorry :(
Is strontium natural or synthetic?
Asked by Wiki User
Its primary ores are strontianite (SrCO3) and celestine/celestite (SrSO4).
How are the Isotopes of strontium alike?
Asked by Wiki User
They have the same number of protons (and of electrons) and so their chemical properties are the same.
What is the use of radionuclide 89 Strontium?
Asked by Wiki User
There are many uses of strontium that nobody would think of. Strontium is used in the fire that is in flares; the kind of flares police men use to tell people to watch out. It is also used for fireworks. Some types of strontium are used to make the glass on a color television tube. It is sometimes used in optical materials such as glasses or telescopes. If a doctor puts a little bit of strontium in a person's body, it is taken up by the bone tissue. Then the doctor uses radiation detectors to locate the radioactive strontium to assess the patents abnormalities.
What group on the periodic table does strontium belong to?
Asked by Wiki User
Strontium is an alkaline earth metal; group 2 and period 5 in the periodic table of Mendeleev.

How many moles of strontium hydroxide are in 4.25 g of strontium hydroxide?
Asked by Wiki User
You must first find the molar mass of the element or compound. Use the periodic table (see the link to the left of the answer). If the chemical is an element, just read off the atomic mass from the periodic table. If it is a compound, you must know the molecular formula, and then you find the total molar mass of the compound by adding up the atomic masses of each atom in the compound. The unit of the molar mass will be in grams per moles (g/mole)
Once you have the molar mass, you can easily convert from grams to moles, and also from moles to grams.
Number of moles = (# of grams) ÷ (molar mass)
Number of grams = (# of moles) × (molar mass)
Here are a two examples:
Example 1:
How many moles are in 5 grams of O2?
The molar mass of O2 = 16.00 g/mole x 2 (for 2 atoms of oxygen) or 32.00 g/mole.
5 g of O2 ÷ (32 g/mole) = 0.15625 moles
Example 2:
How many grams does 4 moles of NH3 weigh?
The molar mass of NH3 = 14.01 + (3 × 1.01) = 17.04 g/mole
4 moles × 17.04 g/mole = 68.16 grams
Grams in a MoleIn chemistry, a mole is considered to be Avogadro's number (6.02 × 1023) of molecules (or anything) of a substance - so depending on the density of the substance, the mass of that amount of the substance could vary widely.One mole of hydrogen, for example, would have a different mass than one mole of lead. The question compares two different measurements of a given substance, rather like asking "how heavy is a gallon?". The question becomes "A gallon of what"?
