a) Calculate, in units of â„, the magnitude of the maximum total(orbital+spin) angular momentum for an electron in a hydrogen atomfor states with a principal quantum number of 5.
b) An electron initially in a 4p state decays to a lower energystate. Which energy state is forbidden? (pick one): 1s, 2s, 3d, or2p? Why?
c) What is the total number of electrons that can occupy asubshell for a given amount of orbital angular momentum l? Write anexpression in terms of l.
