Nitrogen has half-filled $p$-orbitals

Vedclass · Answer

(A) The electronic configuration of Nitrogen $(N)$ is $1s^2 2s^2 2p^3$,which contains a half-filled $p$-orbital. This half-filled configuration provides extra stability to the atom. Due to this increased stability,more energy is required to remove an electron from the $2p$-orbital of Nitrogen compared to Oxygen $(1s^2 2s^2 2p^4)$,which has a less stable configuration.

The ionization energy of nitrogen is more than that of oxygen because
