Answer 2

In chemistry, the valency of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules.

The atomic number is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus.
