Two electrons occupying the same orbital are distinguished by:

A

azimuthal quantum number

B

spin quantum number

C

principal quantum number

D

magnetic quantum number

Text Solution

Verified by Experts

The correct Answer is:
B
Electrons occupying the same orbital of an atom have same value for principle quantum number, azimuthal quantum number and magnetic quantum but differ in their spin quantum number. If one has `+ (1)/(2)`, the other has `- (1)/(2)`
