For an electron in a hydrogen atom (a) when the electron is in the ground state, calculate (r) and (r2) in terms of the bohr radius (b) when the electron is in the ground state, calculate (x) and (y2) in terms of the bohr radius. do not try to integrate to calculate the expectation values! you can do it in smarter way! a (c) when the electron is in the state n = 2,1 = 1, m = -1, calculate (r2).
