                The following quantum numbers are possible for how many orbital n = 3, 1 = 2, m = +2:

A)                 1                            

B)                 2                             

C)                 3                             

D)                 4

Correct Answer: A

Solution :

                n = 3                 \[l=2\]                 m = + 2                 \[s=\,\,\pm \,1/2\]                 These values of quantum numbers are possible for an orbital of 3d sub-shell as the possible value of m for \[l=2\] is
