Answer
Please see the work below.
Work Step by Step
For a principal quantum number ‘n’, angular momentum quantum number $l$ can have values ranging from 0 to (n-1).
If n = 3,
Possible values of $l$ are = 0, 1, 2.
For an angular quantum number ‘$l$’ , Magnetic quantum number $m_{l}$ can have values ranging from - $l$ through zero to +$l$ .
If $l$ = 0,
Possible value of $m_{l}$ = 0
If $l$ = 1,
Possible values of $m_{l}$ = -1, 0, +1
If $l$ = 2,
Possible values of $m_{l}$ = -2, -1, 0, +1, +2.
