A) Sketch a separate diagram for the energy levels of the electron in the Hydrogen atom – The diagram should be to scale. Annotate the diagram with the ground state energy E0, the principal quantum number n, and the ionization energy of the atom (13.6 eV).
B) It is known that a certain hydrogen atom has n=5 and m=2. How many different states are consistent with this information?
C) Answer the same question (in terms of n and m) for arbitrary values of n and m.
D) There are many ways of expressing the classical limit of quantum mechanics. State one of them
