Two electrons occupying the same orbital...

Two electrons occupying the same orbital are distinguished by :

A

Magnetic quantum number

B

Azimuthal quantum number

C

Spin quantum number

D

Principal quantum number

Text Solution

Verified by Experts

The correct Answer is:
C
Two electrons occupying the same orbital has equal spin but the directions of their spin are opposite. Hence, spin quantum number, s, (represented +1/2 and -1/2) distinguishes them.
