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.

Valence, Covalence, Hypervalence, Oxidation State, and Coordination Number  Derek W. Smith
It is argued that the terms valence, covalence, hypervalence, oxidation state, and coordination number are often confused and misused in the literature. It is recommended that use of the term valence, and its associated terminology, should be restricted to simple molecular main group substances and to some oxoacids and derivatives, but avoided in both main group and transition element coordination chemistry.

Teaching Molecular Geometry with the VSEPR Model  Ronald J. Gillespie
The difficulties associated with the usual treatment of the VB and MO theories in connection with molecular geometry in beginning courses are discussed. It is recommended that the VB and MO theories should be presented only after the VSEPR model either in the general chemistry course or in a following course, particularly in the case of the MO theory, which is not really necessary for the first-year course.

A Comment on Molecular Geometry   Frank J. Gomba
A method of determining the correct molecular geometry of simple molecules and ions with one central atom is proposed. While the usual method of determining the molecular geometry involves first drawing the Lewis structure, this method can be used without doing so. In fact, the Lewis structure need not be drawn at all. The Lewis structure may be drawn as the final step, with the geometry of the simple molecule or ion already established.

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.

Simplified Lewis Structure Drawing for Nonscience Majors  Barnabe B. Miburo
