What is the total number of states?

  1. May 30, 2009 #1
    1. The problem statement, all variables and given/known data

    The ρ- meson has a charge of -e, a spin quantum number of 1, and a mass 1507 times that of the electron. The possible values for its spin magnetic quantum number are -1, 0, and 1. Imagine that the electrons in atoms were replaced by ρ- mesons. Select all of the following which are possible sets of quantum numbers (n, l, ml, s, ms) for ρ- mesons in the 2p subshell.

    What is the total number of states?

    2. Relevant equations

    n = 2
    l = 1
    ml = -1, 0, 1

    3. The attempt at a solution

    2 1 1 1 -1
    2 1 1 1 0
    2 1 1 1 +1
    2 1 0 1 -1
    2 1 0 1 0
    2 1 0 1 +1
    2 1 -1 1 -1
    2 1 -1 1 0
    2 1 -1 1 +1

    Total states = 9 (?)

    Do I also count the 2s states or is this question asking for 2p only? I'm confused. Any help is greatly appreciated, thank you!

    Looks good. The question does specifically say 2p.
