Statement : For n=3,l may be 0,1 and 2, and (m) may be 0 , 0, +- 1, and 0, +- 1 and +- 2 . Explanation : For each value of (n) there are 0 to ( n-1) possible values of l , and for each value of l there are (0) to +- 1 values of (m).

Assertion (A) : For n = 3,l1 may be 0,1 and 2 and m may be 0, +- 1 and 0,+- 1 , and +- 2 Reason (R ) : For each value of n, there are 0 to (n - 1) possible value of l for eachvalue of l , there are 0 to +-l valie of m

Statement -1:- For n=2 the values of l may be 0,1 and m may be 0,+- 1. Statement -2 :- for each value of n, there are 0 to (n-1) possible values of l for each value of la there are 0 to +- l values of m.

For each value of l the possible value of m_(1) are………

List the values of l and m_(1) for n=1 .

List all the values of l and m_(1) for n=2 .
