Question
If the nitrogen atom has electronic configuration 1s7, 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
Options
A.Heisenberg’s uncertainty principle
B.Hund’s rule
C.Pauli’s exclusion principle
D.Bohr postulate of stationary orbits
Solution
Pauli’s exclusion principle limits the maximum capacity of electrons in an orbital equal to 2.
