Answer 2

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

Valency is mainly concerned with number of valence electrons or 8 minus number of electrons present in the outermost shell. Number of valence electrons increases upto group IV and then starts decreasing due to addition of electrons in the same shell.
