If the nitrogen atom has electronic conf...

If the nitrogen atom has electronic configuration `1s^(7),` it would have energy lower than that of the normal ground state configuration `1s^(2)2s^(2)3p^(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 postulate of stationary orbits

Text Solution

Verified by Experts

The correct Answer is:
C
According to Paull.s exclusion principle an orbtial cannot have more than two electrons and these two with opposite spin.
Hence c, is the correct answer.
