Nitrogen has the electronic configuration `1s^(2)2s^(2)2p_(x)^(1)2p_(y)^(1)2p_(z)^(1)` and not `1s^(2)2s^(2)2p_(x)^(2)2p_(y)^(1)2p_(z)` as it violates.

A

Hund's rule

B

Pauli's exculsion principle

C

Aufban principle

D

`(n +l)` rule

Text Solution

Verified by Experts

The correct Answer is:
A
According to Hund's rule, electron pairing in `p,d`, and `f` subshells cannot occur unit each orbital of a given subshell contains one electron each or is singly occupied.
