The Mechanism of Covalent Bonding: Analysis within the Hückel Model of Electronic Structure  Sture Nordholm, Andreas Bäck, and George B. Bacskay
Hckel molecular orbital theory is shown to be uniquely useful in understanding and interpreting the mechanism of covalent bonding. Using the Hckel model it can be demonstrated that the dynamical character of the molecular orbitals is related simultaneously to the covalent bonding mechanism and to the degree of delocalization of the electron dynamics.

Probing the Orbital Energy of an Electron in an Atom  James L. Bills
This article answers an appeal for simple theoretical interpretations of atomic properties. A theoretical snapshot of an atom, showing the screened nuclear charge and the electron to be ionized at its radius of zero kinetic energy, enables anyone to approximate its ionization energy.

The Genius of Slater's Rules  James L. Reed
With only a few modifications a procedure has been developed that yields the one-electron energies for atoms and ions with a level of detail very well suited for instruction in the structure and properties of atoms. It provides for the computation of very reasonable values for such properties as ionization energies, electron affinities, promotion energies, electronic transitions, and even XPS and ESCA spectra.

Deducing the Shell Model from Ionization Energies and the Use of Models in Introductory Chemistry  Ronald J. Gillespie, Richard S. Moog, and James N. Spencer
A major objection of Rioux and DeKock is the statement in the authors' earlier paper that electron repulsion is responsible for the relative ionization energies of H and He. The commentators work clearly shows that a quantum mechanical treatment of this problem reveals that kinetic energy considerations play a crucial role in these values. However, although their criticism is appropriate in the context of this more sophisticated QM treatment, it does not in any way invalidate the authors original paper, the goal of which was to provide a model, namely the shell model, for the electronic structure of atoms that is consistent with experimental ionization energies.
