There is a long derivation to prove this requiring a theorem which i think is not even included in M.Sc. So don't stress urself out too much.
Btw, I haven't studied much about spin q. no. till now(just one class!) but my teacher said that there is a single orbital and according and the electrons...
Hello. I am in class eleventh. I met a class 12th guy telling me that he knew a theoretical proof for showing that the values of spin quantum number are +1/2 and -1/2.
If anyone else knows the proof, please tell me...I'm desperate to know..
Any help would be appreciated.
