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.
the valency is 4
Its valency is 0.
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 for nitrite is 5
magnesium has a valency of 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 of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +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.
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.
