Question

Why is Nitrogen an Inert gas?

Answer 1

Nitrogen is chemically inert under ordinary atmospheric conditions. Nitrogen is a diatomic molecule,$\left(\mathrm{N}\equiv \mathrm{N}\right)$.The molecule has one sigma and two $\mathrm{\pi }$-bonds. The dissociation energy is very large (225 kcal mol^-1) and thus, is stable and inert under ordinary conditions.
