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.

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 correct interpretation of Hund's rule as applied to "uncoupled states" orbital diagrams  Campbell, Mark L.
The application of Hund's rule by general chemistry students is appropriate as long as Hund's rule is interpreted correctly.

Using the Aufbau principle   Whitmer, John C.
This question is written with the belief that general chemistry students should not only attain an understanding of the Aufbau principle enabling them to write down electron configurations, they ought also recognize the correspondence between the quantum numbers and the structures of the periodic table.

Nuclear concepts as part of the undergraduate chemistry curriculum  Caretto, A. A., Jr.; Sugihara, T. T.
It is proposed that there are distinct advantages to a freshman curriculum that introduces nuclear concepts simultaneously with the discussion of analogous atomic and molecular concepts.

Tangent-sphere models of molecules. III. Chemical implications of inner-shell electrons  Bent, Henry A.
While a study of atomic core sizes might seem to hold little promise of offering interesting insights into the main body of chemical theory, it is demonstrated here that from such a study emerges a picture of chemical bonding that encompasses as particular cases covalent, ionic, and metallic bonds.

A new periodic table based on the energy sequence of atomic orbitals  Walker, W. R.; Curthoys, G. C.
Since the theory of atomic and molecular orbitals has proven to be of such value in interpreting the data of inorganic chemistry, it is hoped that a new periodic table based on the energy sequence of atomic orbitals will be an aid to the further systematizing of chemical knowledge.
