Question

define valency. what conclusion can be drawn about the relativity of an at
om from its valency

Answer 1

An atom will always try to acquire an octet or acquire a state of stability by giving,taking or sharing electrons.The valency of an atom determines its combining capacity or the no. of electron it will gain,lose or share to become stable.

For eg= chlorine's electronic configuration=2,8,7

And it will gain 1 electron to become stable hence,its valency=1

hope it helps you!!

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.
