Variable valencies are the valencies which can change e.g. Fe (iron) can either have the valency of 2 (Fe II) or 3 (Fe III)

The valency of lithium is 1. It has one valence electron in its outer shell.
Atomicity, what a charming old word. Used to mean either valency or the number of atoms in a molecule. For silicon the valency is 4. (where valency was the numebr of bonds that could be formed) Silicon is not molecular, it is normally encountered as a solid with a network lattice.
the valency is 4
Its valency is 0.
The valency of halogens is 1, meaning they can form one bond with another element. This valency indicates how many electrons halogens need to gain in order to achieve a full outer shell and become stable.
The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2
The valency of ferricyanide is -3. It contains one iron (III) cation with a valency of +3 and one cyanide anion with a valency of -1.
The valency of silver is typically +1. However, silver can also exhibit a valency of +2 in certain compounds.
the valency for nitrite is 5
magnesium has a valency of 2
The valency of potassium dichromate is +6. This is because potassium has a valency of +1, and each chromium atom in the dichromate ion has a valency of +6.
