(1) an atomic orbital has n=3. what are the possible values of l and `m_(l)`?
(2) List the quantum numbers (`m_(l) and l`) of electrons for 3d orbital.

Explanation

(1) If n=3, then l=0,1,2
When l=0, `m_(l)=0,` when l=1, `m_(l)=-1,0,+1`,
`m_(l)=-2,-1,0,+1,+2`.
(2) For 3d-subshell, n=3 and l=2, for l=2, `m_(l)=-2,-1,0+1,+2`
