Nitrogen has half-filled $p$-orbitals

(A) The electronic configuration of Nitrogen $(N)$ is $1s^2 2s^2 2p^3$,which contains a half-filled $p$-orbital.This half-filled $p$-orbital configuration is exceptionally stable.Therefore,more energy is required to remove an electron from the stable half-filled $p$-orbital of Nitrogen compared to the $2p^4$ configuration of Oxygen.
