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.

The Mechanism of Covalent Bonding: Analysis within the Hückel Model of Electronic Structure Sture Nordholm, Andreas Bäck, and George B. Bacskay
Hckel molecular orbital theory is shown to be uniquely useful in understanding and interpreting the mechanism of covalent bonding. Using the Hckel 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.

On the Role of d Orbital Hybridization in the Chemistry Curriculum John Morrison Galbraith
The use of d-orbital hybridization to describe hypervalent molecules should be removed from the general chemistry curriculum. The case of bonding in sulfur hexaflouride can illustrate that no theory provides all the right answers all the time.

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.
