MCQ
Electron occupies the available orbital singly before pairing in any one orbital occurs, it is
- APauli's exclusion principle
- ✓Hund's Rule
- CHeisenberg's principle
- DProut's hypothesis
✓
Answer
Correct option: B.
Hund's Rule
b
Hund's Rule: evey obital in a shell is singly occupied with one $e^\theta$ before any one orbital is doubly occupied, and all $e^\theta$ in singly occupied orbitals have the same Spin.
