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.

Answer 2

Answer:

Valency is the combining capacity of an element with other element.

Valency can be calculated if :

• there are less than 4 electrons in the outermost shell : Valency = 1,2 or 3 (depending upon number of electron)

• there are four or more electrons in outermost shell : Valency = 8 - number of electrons.
