What are the possible values of l for each of the following values of n ?
n=1,2,3,4 
What are the possible values of ml for each of the following values of l?
l=0,1,2,3
Answer:
 The possible values of l is from 0 to n1.
So, when n=1, l=0
when n=2, l=0, 1
when n=3, l=0, 1, 2
when n=4, l=0, 1, 2, 3  The possible values of ml is from 0 to l, both positive and negative values.
So, when l=0, ml=0
when l=1, ml= 0, 1, 1
when l=2, ml= 0, 1, 1, 2, 2
when l=3, ml= 0, 1, 1, 2, 2, 3, 3
