Determine whether each of the following sets of quantum numbers for the hydrogen atom are valid. If a set is not valid, indicate which of the quantum numbers has a value that is not valid:

(a) n = 4, l = 1, ml = 2, ms = -12

(b) n = 4, l = 3, ml = -3, ms = +12

(c) n = 3, l = 2, ml = -1, ms = +12

(d) n = 5, l = 0, ml = 0, ms = 0

(e) n = 2, l = 2, ml = 1, ms = +12
