The Noble Gas Configuration—Not the Driving Force but the Rule of the Game in Chemistry  Roland Schmid
Explains the covalent and ionic bonding behavior of main-group elements in terms of electromagnetic forces rather than the supposed "stability" of noble-gas configurations.

Electron Densities, Atomic Charges, and Ionic, Covalent and Polar Bonds  Ronald J. Gillespie
The terms ionic and covalent character are vague, qualitative, and ill-defined. In contrast, the analysis of the electron density by the AIM theory leads to clearly defined quantitative properties such as the charges on the atoms and the electron density at the bond critical point that provide a sound basis for discussing bonding and geometry.

The Use of Molecular Modeling and VSEPR Theory in the Undergraduate Curriculum to Predict the Three-Dimensional Structure of Molecules  Brian W. Pfennig and Richard L. Frock
Despite the simplicity and elegance of the VSEPR model, however, students often have difficulty visualizing the three-dimensional shapes of molecules and learning the more subtle features of the model, such as the bond length and bond angle deviations from ideal geometry that accompany the presence of lone pair or multiple bond domains or that result from differences in the electronegativity of the bonded atoms, partial charges and molecular dipole moments, and site preferences in the trigonal bipyramidal electron geometry.

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.

The Role of Electrostatic Effects in Organic Chemistry  Kenneth B. Wiberg
Electrostatic effects on the properties of organic compounds are reviewed to demonstrate the importance of electronegativity differences between the atoms forming a bond. Bond dissociation energies are generally found to increase as the electronegativity difference increases, and the bonds have increased ionic character.

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.
