Question

For n=2 shell,how many number of electrons with S=+1/2 and m=0?

Answer 1

Answer:

Two

Explanation:

It is because in n=2 there are 2 sub shells s and p.

In s sub shell e having m=0 and s=+1/2 is 1.

In p sub shell there is only one orbital having m=0 ie. pz and that orbital also contain only 1 e with s=+1/2 .

So the correct answer is 2.
