Answer 2

Valency is one of the most important chemical properties of a chemical compound.

And there are different types of valency,and similarly the valency which happens through the mutual sharing of paired electrons are known as the covalency.

The covalency is calculated by the number of electrons shared by an element to form the covalent electron pairs.
