Quantum numbers

  1. Apr 15, 2014 #1
    1. The problem statement, all variables and given/known data
    Why isn't (3, -2 , 0 , 1/2) a valid quantum number?


    2. Relevant equations



    3. The attempt at a solution
    n=3

    so l = -2 is valid.

    -l≤Ml≤l

    2≤Ml≤-2
    nonsensical statement. I don't know what to do....

    No, l=-2 is not valid. l is always non-negative.

    Ah so it's that simple... Thanks.

    I agree.
    n = 3
    l = 0, 1, 2
    ml = -2, -1, 0, 1, 2
    ms = -1/2 or 1/2

    l cannot be negative, but ml can be.
