(1) Calculate (r) and (r²) for the ground state of the hydrogen atom, expressing your answer in term of the Bohr radius. Calculate (x) and (x²) for the ground state of the hydrogen atom. Note that you really do not have to do any more work than you already did in problem #1 if symmetry properties are invoked.
