Question

which of the following sets of quantum numbers do not belong to 2p subshell and why
1)n=2,1=1,m=+1,s=+1/2
2)n=2,1=0,m=0,s=-1/2
3)n=1,1=1,m=0,s=+1/2​

Answer 1

Answer:

2 and 3, because  for p value of l should be 1

in 2  l=0 it is 2s not 2p

3) n=1 l=1 it is 1p which even doesnt exist

so your ans is 1)
