Question

why nitrogen is called inactive gas?​

Answer 1

The triple bond is covalent in nature and it is non-reactive in normal conditions. The triple bond present in nitrogen is very strong. Therefore, it requires a lot of energy to break those bonds to take part in a reaction.

Hence , nitrogen is commonly referred to as an inert gas.

Answer 2

Explanation:

Molecular nitrogen is a colorless, odorless, tasteless, and inert gas at normal temperatures and pressures. ... The strong triple-bond between the atoms in molecular nitrogen makes this compound difficult to break apart, and thus nearly inert.
