Question
If the nitrogen atom had electronic configuration1s7,it would have energy lower than that of the normal ground state configuration 1s2 2s2 2p3,because the electrons would be closer to the nucleus.Yet,1s7 is not observed because it violates.
- He is enbergun certainty principle
- Hund’s rule
- Pauli’s exclusion principle
- Bohr postulates of stationary orbits.
The correct answer is: Pauli’s exclusion principle
