Periodic properties of the elements

Question

Give all possible values of l if n= 3

Answer 1

The l values (angular momentum quantum number) correspond to the sublevels present in the energy level (n).

For n=3, we would expect 3s, 3p, and 3d, so the possible l values are 0,1, and 2.

Another way to remember is that the l values are 0 to (n-1).
