(i) Calculate and the standard deviation in r for a 2px electron. Compare this against your results for an electron in the 1s and 4s orbitals.

(ii) Calculate the standard deviations in x and y for a 2px electron. The calculation can be done in either Cartesian or spherical coordinates, but Mathematica will have an easier time with spherical coordinates. Do the relative magnitudes of these quantities make sense?
