Computational studies have determined the effective nuclear charge, Zeff, for an electron in a particular subshell to a high degree of certainty. The table lists the calculated Z eff values for a 1s, 2s, and 2p orbital of lithium. From the provided values of effective nuclear charge, estimate the energy, n, of a 1s, 2s, and 2p orbital of lithium. A rydberg (Ry) is a unit of energy approximately equal to 13.6 eV. 1s = 2s = 2p= Ir Li 1s 2s 2p Zeff 2.69 1.28 1.02 Ry Ry Ry In terms of the Bohr radius, a, estimate the average distance of the electron from the nucleus, n,e, for an electron in a 1s, 2s, and 2p orbital of lithium.
