Physical observables determined by quantum numbers: n, l, ml, ms

  1. Apr 12, 2010 #1
    exam practise question:

    what are the physical observables determined by the quantum numbers n, l, ml and ms of the electron in a hydrogen atom.

    most places just give the equation or the name not the physical observable determined.
    so is this right?:-

    n = principal number determines the energy state that th atom is in
    l = azimuthal number i know is to do with the orbital angular momentum, does this determine the angular momentum state?
    ml = magnetic quantum number associated with angular momentum
    ms = magnetic quantum number associated with spin and if we have spin +1/2 then the electron will have a higher energy then if it was -1/2

    and thats all i know.
    any help would be great.
