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.

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.

Let Us Give Lewis Acid–Base Theory the Priority It Deserves  Alan A. Shaffer
The Lewis concept is simple yet powerful in its scope, and can be used to help beginning students understand reaction mechanisms more fully. However, traditional approaches to acid-base reactions at the introductory level ignores Lewis acid-base theory completely, focusing instead on proton transfer described by the Br?nsted-Lowry concept.

Entropy and the Shelf Model: A Quantum Physical Approach to a Physical Property  Arnd H. Jungermann
A quantum physical approach relying on energy quantization leads to three simple rules which are the key to understanding the physical property described by molar entropy values.

Valence, Oxidation Number, and Formal Charge: Three Related but Fundamentally Different Concepts  Gerard Parkin
The purpose of this article is to clarify the terms valence, oxidation number, coordination number, formal charge, and number of bonds and illustrate how the valence of an atom in a molecule provides a much more meaningful criterion for establishing the chemical reasonableness of a molecule than does the oxidation number.

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.
