What is the valency of inert gas?

Open in App

Solution

Valency
The combining power (or capacity) of an element is known as its valency.
Valency of inert gas
The general electronic configuration of inert gas is $n s^{2} n p^{6}$ except for helium.
The electronic configuration of inert gases is stable.
They do not lose, gain, or share electrons.
Thus the valency of inert gas is zero.
