Question

The claim is made in Section 9.5 that a d electron is screened more effectively from the nuclear charge in an atom than is a p electron or an s electron. Give a classical argument based on the definition of angular momentum L=r x p that indicates that smaller values of angular momentum are associated with orbits of larger eccentricity. Verify this quantum mechanically by calculating the probability that a 2p electron of hydrogen will be found inside n=1 atomic shell and comparing this with the probability of finding a hydrogen 2s electron in this same region. For which is the probability largest, and what effect does this have on the degree of screening?
