Indicate which of the following quantum states are allowed and which are
disallowed under the rules governing the electronic structure of atoms.
n = 2, l = 1, ml = 0, ms = ½
n = 3, l = 3, ml = -2, ms = -½
n = 4, l = 3, ml = -2, ms = ½
n = 3, l = 2, ml = 2, ms = ⅓
n = 2, l = 1, ml = -2, ms = -½
n = 3, l = 2, ml = -1, ms = -½

    You must know the rules which are
    n may be any whole number >1.
    l may be a whole number from 0 to n-1; i.e., 0, 1, 2, 3, etc.
    m may be any whole number from -l to +l including zero
    s may be either +1/2 or -1/2.

    For example, 1 is allowed but 2 is not.
    (2 is not allowed because if n = 3 then l may not be larger than n-1 = 2.)That's how it's done.
