Compare the solubilities of the lead compounds with those of the alkaline earth metals How are the solubilities similar and different?
Look at the position of Pb in the periodic table and the postion of the Alkali Earth metals. Alkali Earth Metals are in noble-gas configuration when they are doubly charged cations. Lead however is on the right hand side, and would like to have more electrons to get into that stablest configuration; making the bonds in lead-compounds more covalent -and stronger- in nature. Insoluble compounds have lattice enthalpies higher than the enthalpy of solvation. Now since Alkali Earth metals like to be in ionic states; their compounds will dissolve in general more easily than the same compounds with lead, since usually the lattice energy of lead compounds is much higher (In case of insoluble compounds higher than the energy that would be released upon solvation, which thus doesn't occur).
What is the oxidation state of beryllium?
the oxidation state of beryllium is +2
Are alkaline earth metals a good conductor of electricity?
Ok this question is a little tricky question. Let us answer this question based on concept of band theory. let us look at group 1 metals. Take the example of Na. It has only one valance electron. Hence the band diagram will be incomplete when sketched and due to this the nature of the element that is Na is metallic and also it exhibits good conductivity.Now let us take the case of group 2 metals. Since the valence electron will be two and both of them will be filled, there will be an overlap of band. This will give it metallic nature but on the contrary since there will not be empty states it will be a poor conductor when compared to group 1.Note: Group 2 metals exhibit conductivity but on a comparative scale with group 1 and 3 they are bad conductors.
Is black widow tattoo ink good?
no!! in the disclaimer states that there are several metals and chemicals used in this ink, including arsenic..
What are the chemical properties of gold?
Gold is called a noble metal because it resists reacting with stuff. But it can be "convinced" to react, and it forms numerous compounds. It's oxidation states range from -1 to +5, with +1 and +3, Au(I) and Au(III), far and away the most common. Gold will dissolve in Mercury, but creates an amalgam rather than react with it to create a compound. Aurum (gold) resists most acids, though aqua regia (a 3:1 mix of concentrated hydrochloric and nitric acids) will attack gold, as will cyanide. In the unusual -1 state, gold will form compounds like CsAu (cesium auride). It will hook up with the most reactive of the Group 1 and Group 2 elements, the Alkali and Alkaline Earth elements. Remember that the activity of these elements increases as you go down the column. That's just the opposite of the Group 17 elements, the halogens (fluorine, chlorine, etc.), whose reactivity increases as you go up the column. Speaking of the halogens, the Group 17 elements, will react with gold (Au), and auric fluoride (gold fluoride, AuFl) and auric chloride (gold chloride, AuCl) would be examples. Gold will form compounds in its +1 oxidation state with other ions, and it will also similarily form a number of compounds in the +3 oxidation state. There are also compounds (cluster compounds) where gold will form a compound that includes both the +1 and +3 oxidation states of the metal. It has "dual" (fractional) oxidation states in a single compound. Links are provided for more information.
Oxides react with oxygen and water and are used to make paints are some of the properties of which type of metals?
Transition metals exhibit these properties. They are known for forming oxides that react with oxygen and water, and are commonly used in various applications such as making paints due to their diverse reactivity and stable oxidation states.
Why transition metals have variable oxidation number?
Transition metals have variable oxidation numbers because they have incompletely filled d orbitals in their outermost electronic shell. These d orbitals can participate in bonding and easily change their oxidation states by gaining or losing electrons. This flexibility allows transition metals to exhibit a wide range of oxidation states in different compounds.
Which elments are cations positive oxidation state?
Some examples of elements that commonly form cations with positive oxidation states include alkali metals such as sodium (Na+) and potassium (K+), alkaline earth metals such as magnesium (Mg2+) and calcium (Ca2+), and transition metals like iron (Fe3+) and copper (Cu+).
Why do chemists use a periodic table?
Because all of the elements are displayed; also they are divided into groups (alkali, alkaline earth, transition metals, metalloids, non metals, halogens, noble gases, lathanides and actinides) based on their reactivity, common oxidation states and properties. This helps chemists to think of chemical compounds and their composition (e.g alkali metals usually have +1 oxidation states, alkaline earth +2 and transition +2,+3, but are not limited to these oxidation states).
Metals that are less reactive that aklitlsnd alkaline earth-metals are called?
Metals that are less reactive than alkali and alkaline earth metals are called transition metals. They are typically less prone to reacting with other elements and have distinctive properties such as variable oxidation states and the ability to form colored compounds.
Do metals have more than one oxidation number?
Yes, some metals can exhibit multiple oxidation numbers due to the ability to lose electrons from different orbitals. These variable oxidation states arise from the different ways in which the electrons in the outermost energy levels can be lost.
Do transitionn metals have a consistent oxidation number?
transition metals have variable oxidation states
What are the elements in group 2 through 12 called in the periodic table?
Elements in group 2 through 12 of the periodic table are known as transition metals. They are characterized by their ability to form multiple oxidation states and their tendency to exhibit colorful compounds.
What are the elements on the periodic table between group 2 and 3 called?
The elements on the periodic table between group 2 (alkaline earth metals) and group 3 (transition metals) are called the transition elements or transition metals. These elements exhibit characteristic chemical properties such as variable oxidation states and the ability to form colored compounds.
What is the oxidation number for einsteinium?
The oxidation number for einsteinium is typically +3. However, it can exhibit other oxidation states in specific chemical compounds.
What is oxidation number of transition elements?
The oxidation number of transition elements can vary because they have multiple oxidation states. Transition metals typically exhibit more than one oxidation state due to the presence of partially filled d orbitals, allowing them to lose a variable number of electrons. Common oxidation states for transition elements range from +1 to +7.
What fills more than one column on periodic table?
Transition metals such as zinc (Zn), cadmium (Cd), and mercury (Hg) are elements that typically fill more than one column on the periodic table due to their variable oxidation states. For example, zinc can exhibit a +2 oxidation state, while mercury can form +1 and +2 oxidation states.
