Question

So whenever am expressing atom in it hybridization should I use the valance electrons?

Answer 1

A single valence electron structure cannot represent it.

Explanation:

A "hybrid" structure is an "average" picture of different atomic states. It can be shown as the equilibrium between states of valence electrons, but a single valence electron structure cannot represent it.

In chemistry, resonance or mesomerism is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by one single Lewis structure
