If the nitrogen atom 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: because the electrons would be closer to the nucleus. Yet 1s^7 is [...]
