If the nitrogen atoms had electronic configuration `1s^7` it would have energy lower than that of the normal ground state configuration `1s^2 2s^2 2p^3` because the electrons would be closer to the nucleus yet `1s^7` is not observed because it violates

A

Heisenberg's uncertainty principle

B

Hund's rule

C

Pauli exclusion principle

D

Bohr's postulates of stationary orbits
