Phosphorous is having three unpaired electrons according to

✓
Hund’s rule
B
Aufbau principle
C
Pauli’s exclusion principle
D
Heisenberg’s principle

✓

Answer

Correct option: A.

Hund’s rule

a
The presence of three unpaired in Nitrogen can be explained by Hund rule. Since, the outermost shell is the $P$ shell and $P$ shell has $3$ orbitals each of these orbitals can accommodate $2$ electron. Then each of these $3$ electron occupies one orbital and remain unpaired.
