Question:
The ground state term symbol for an electronic state is governed by
The ground state term symbol for an electronic state is governed by

Updated On: Apr 20, 2026
- Heisenberg principle
- Hund's rule
- Aufbau principle
- Pauli exclusion principle
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Term symbols describe the overall angular momentum of an atom. Ground state term is determined by Hund's rules.
Step 2: Detailed Explanation:
Hund's rule: (1) Maximum multiplicity (maximum total spin S); (2) Maximum total orbital angular momentum L for that S; (3) For less than half-filled, J = |L-S|; for more than half-filled, J = L+S. This gives the ground state term symbol.
Step 3: Final Answer:
Hund's rule
