Question:
Presence of 3 unpaired electrons in nitrogen can be explained by ____ principle.
Presence of 3 unpaired electrons in nitrogen can be explained by ____ principle.
Updated On: Apr 28, 2025
- Aufbau
- Pauli
- Hund
- Bohr

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Hund’s Rule states that electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up. This explains why nitrogen has 3 unpaired electrons in its 2p-orbitals, as the 2p orbitals are degenerate and Hund’s rule applies.
Thus, the correct answer is Hund.
