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