Lewis Structure Representation of Free Radicals Similar to ClO  Warren Hirsch and Mark Kobrak
An unconventional Lewis structure is proposed to explain the properties of the free radical ClO and a series of its isoelectronic analogues, particularly trends in the spin density of these species.

Moving Beyond the Single Center—Ways To Reinforce Molecular Orbital Theory in an Inorganic Course  Marion E. Cass and William E. Hollingsworth
Rather than ending the discussion of molecular orbital (MO) theory in an inorganic chemistry course with molecules such as octahedral ML6 or square planar ML4, we suggest moving beyond the single-atom center to include the MO diagram of ethene (C2H4).

Lewis Structures Are Models for Predicting Molecular Structure, Not Electronic Structure  Gordon H. Purser
This article argues against a close relationship between Lewis dot structures and electron structure obtained from quantum mechanical calculations. Lewis structures are a powerful tool for structure prediction, though they are classical models of bonding and do not predict electronic structure.

Teaching Chemistry with Electron Density Models  Gwendolyn P. Shusterman and Alan J. Shusterman
This article describes a powerful new method for teaching students about electronic structure and its relevance to chemical phenomena. This method, developed and used for several years in general chemistry and organic chemistry courses, relies on computer-generated three-dimensional models of electron density distributions.

Bond energies in the interpretation of descriptive chemistry  Howald, Reed A.
Most of the discrepancy between bond energies and bond dissociation energies is eliminated by the inclusion of pi bonding effects and using bond energies referred to as hypothetical "valence state" atoms in those cases where spin pairing provides substantial stabilization for the free atom.
