Question

Find no. of electrons for which n=2, m=0, s=+½.​

Answer 1

Answer:

Answer is 1 electron

Explanation:

N=2 means p shell

L=1 (l of second shell=1)

So p subshell has 3 orbital

Whose value of M=-1,0,1

But we have to take M=0

So total no. Of electron present in m=0 is 2

Now this orbital has Two electron one has s=+1/2 and other has s=-1/2

As per the question only s=+1/2 is required

So total no. Of electron having M=0 and S=+1/2 is only 1
