**DrBob222**, Monday, October 29, 2012 at 9:57pmHere are the rules.

n can be any whole number over zero; i.e., 1, 2, 3, 4, etc.

l ("ell") can be any whole number beginning with zero, 1, 2, 3, etc with a maximum of n-1.

m_{l}= - ell to + ell in whole numbers;i.e., if ell is 2 then m_{l}can be -2,-1,0,+1,+2.

m_{s}may have two values only; i.e., +1/2 or -1/2

Your job is to take these rules and apply them to each of the above and find those that are allowed. To give you a fast start

#1 is allowed.

#2 is not allowed. Why not? If N is 4, then l CAN be 2 (l can have values in this case of 0,1,2,3) so 2 is allowed. However, m_{l}CANNOT be 3 because m_{l}may take values from -l to +l (in whole numbers) which will allow -2,-1,0,+1,and +2 but not +3.
