Question:

The relative penetration of the inner-core electrons by the outer electron in sodium can be described by the calculation of Zeff from E = - [Z2 eff(13.6) eV]/n2 and comparing with E = -13.6 eV/n2 for no penetration.

(a) Find the energies of the outer electron in the 3s, 3p, and 3d states from Figure 7-22.

(b) Find Zeff for the 3p and 3d states. 

(c) Is the approximation -13.6 eV/n2 good for any of these states?
