You must know the rules Here they are.
n may be any whole number from 1 (that is, 1, 2, 3, 4, 5, etc)
l may take values of 0 and increase by increments of 1 but may not be larger than n-1. (Therefore, for n = 1, l may be zero only. For n = 2, l may be 0 or 1)
ml may have values from -l up to +1 with all values between in whole numbers, including 0.
Ms may have values of +/- 1/2.
The first one:
Starting with n = 4, we know l may be 0, 1, 2, or 3 so l = 3 is ok.
ml may have values of -3, -2, -1, 0, +1, +2, and +3 (that's -l to +l). It CAN'T have a value of 4 so that's what is wrong with that set.
You do the second one the same way. Jut analyze it step by step.
What is wrong with these sets? Fix what's wrong:
n=4, l=3, ml=4
n=2,l=-1, ml=1
I don't exactly even know what the question is asking!

Okay, I understand now, it's much easier than I was making it out to be! Thanks so much for your help!
