A New "Bottom-Up" Framework for Teaching Chemical Bonding  Tami Levy Nahum, Rachel Mamlok-Naaman, Avi Hofstein, and Leeor Kronik
This article presents a general framework for bonding that can be presented at different levels of sophistication depending on the student's level and needs. The pedagogical strategy for teaching this model is a "bottom-up" one, starting with basic principles and ending with specific properties.

News from the Periodic Table: An Introduction to "Periodicity Symbols, Tables, and Models for Higher-Order Valency and Donor–Acceptor Kinships"  Henry A. Bent and Frank Weinhold
Proposes that alternative display topologies such as a 2D "left-step" or "step-pyramid" table or 3D "periodic towers" can supplement or supplant the standard periodic table by better emphasizing higher-order patterns of chemical association and reactivity, rather than the physical resemblances of standard-state elemental substances.

Have Orbitals Really Been Observed?  Eric R. Scerri
Recent reports claiming to have observed textbook d orbitals are analyzed and it is argued that what was observed indirectly, and not for the first time, was actually electron density. It is also suggested that the tendency to use the terms electron density and orbital to mean the same thing will give rise to confusion in chemical education.

Ionization Energies, Parallel Spins, and the Stability of Half-Filled Shells  Peter Cann
Three methods for explaining the decrease in first ionization energies between group V and group VI elements are described and commented upon. The quantum mechanical origin of the unhelpful concept of half-shell stability is explained in terms of exchange energy, for which the alternative term parallel spin avoidance factor is suggested. It is recommended that for pre-university students the simplest explanation, in terms of Coulombic repulsion between two electrons occupying the same orbital, is adopted: it involves fewer difficult concepts than the other explanations and its predictions are no less accurate.

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.

How Good Is the Quantum Mechanical Explanation of the Periodic System?  Eric R. Scerri
The use of quantum mechanics, or more specifically, orbitals and electronic configurations in teaching general chemistry is now such a widespread trend that it would be utterly futile to try to reverse it. Moreover, orbitals and configurations have been extremely useful in providing a theoretical framework for the unification of a multitude of chemical facts.

Experimental 4s and 3d Energies in Atomic Ground States  James L. Bills
A new definition is given for the effective charge Zf. HF orbital energies e4s and e3d are used in concert with I4s and I3d to answer four questions: Why does the 4s sublevel fill before 3d? Why is ionization easier for 4s than 3d? When 4s23dn has e3d < e4s, why doesn't 4s23dn -> 4s13dn+1? Why are Cr and Cu each 4s13dn+1 instead of 4s23dn?

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.

In Defense of Quantum Numbers  Robert M. Richman
A recent paper has argued that the derivation of the periodic table using quantum numbers is a topic that should be eliminated from introductory chemistry courses because it is too abstract, mysterious, and esoteric. A rebuttal is offered based on the claim that it would be wrong to omit discussions of the inductive approach of Mendeleev and the deductive approach initiated by Schroedinger, because they compose the consummate example of that interaction of empirical and rational epistemologies that defines how chemists think.
