Which sets of quantum numbers are not allowed?

and why?

(a) n = 3, l = 2, ml = 2

(b) n = 4, l = 3, ml = 4

(c) n = 0, l = 0, ml = 0

(d) n = 2, l = -1, ml = 1

(e) n = 1, l = 1, ml = 2

    (a) n = 3, l = 2, ml = 2 <<<OK

    (b) n = 4, l = 3, ml = 4 <<<Not OK. -l<= ml <=l (ells, not ones)

    (c) n = 0, l = 0, ml = 0 <<<Not OK. minimum value for n = 1.

    (d) n = 2, l = -1, ml = 1 <<<Not OK. l can't be negative. (0 <= l <= n-1)

    (e) n = 1, l = 1, ml = 2 <<<Not OK. same as (b). (max value for ml =1 when l = 1.

    Is ml=0, ms= +1/2 allowable?
