Consider the electron in a 2p state (for simplicity, take m = 0) (i) consider whether and < 1/r> can be calculated by integrating only the radial part of the wavefunction. (ii) calculate the expectation value of the distance between the electron and the nucleus, (ii) calculate the expectation value of the reciprocal distance between the electron and the nucleus, < 1/r> . (iv) are the average potential energies of the electron in 2s and 2p states the same or different?
