Quantum mechanics problem: hypothetical spin quantum number and its

  1. Sep 12, 2012 #1
    So we are doing problems involving potential energy of electrons, wave functions, and all that jazz, but I am utterly lost on how to do this problem... The professor threw it at us, and I am completely lost on how to even begin. Please help me

    In a different universe from ours the spin quantum number for the electron is observed to be s= 5/2 instead of 1/2 but all other properties of the electron are the same as in ours.

    (a) Describe qualitatively the outcome of a Stern-Gerlach experiment on hydrogen atoms in this

    (b) What are the possible values of sz for the electron in this universe and what are the possible angles that the spin angular momentum can make with the z-axis?

    (c) Calculate the value of s^2
    for the electron in this universe.

    (d) How many elements will be present in the first row of the periodic table in this universe? Why?
