How many quantum numbers in the subshells?

An excited hydrogen atom undergoes a transition, in which an electron moves from n= 5 to another orbital and a photon with a wavelength of 1282nm is emitted. What orbital does the electron occupy after this transition? a) n =1 b) n = 2 c) n = 3 d) n = 4 e) n = 6 f) This is not a possible transition and none of the other responses are correct.

Pick all of the combinations of atomic quantum numbers that cannot occur: (Can be more than 1 answer choice) n=3, l=2, m=2 n=0, l=0, m=0 n=2, l=2, m=0 n=7, l=3, m=-3
