MCQ
Phosphorous is having three unpaired electrons according to
- ✓Hund’s rule
- BAufbau principle
- CPauli’s exclusion principle
- DHeisenberg’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.
