Can anyone tell me which of the following quantum number combinations is not allowed in an atom?
Medal to best response?

n = 2, l = 1, m = 0

n = 1, l = 0, m = 0

n = 4, l = 3, m = -3

n = 2, l = 3, m = 2

MAin quantum number n = 1,2,3,.. for atomic energy levels K,L,M,...
Side quantum number l may have values 0,1, ... n-1
magnetic quantum number m = -l ,... 0, ...l
e.g.  l = 2 ,  m = -2,-1,0,1,2

So it would be C?

No. D. Because l can not be greater than n.
