why electron has half spin but not any other number

Answers : (1)


Dear umar

There are two and only two possible values for the component m_L of this angular momentum along any given direction.  
The number of values of m_L for any value of L in quantum mechanics is always equal to 2 times L plus 1, so L must be 1/2
when exactly two values of m_L are seen.

We are all IITians and here to help you in your IIT JEE preparation.

All the best.
