Describes an experiment that introduces students to integrated rate laws, the search for a mechanism that is consistent with chemical and kinetic data, and the concept of activation barriers and their measurement in a curriculum whose pedagogical philosophy makes the laboratory the center of learning for undergraduates in their first two years of instruction.

A Colorful Look at the Chelate Effect  Donald C. Bowman
The relative stabilities of several copper(II) and nickel(II) complexes are visually compared by noting color changes due to ligand exchange reactions. The demonstration illustrates the chelate effect┬Łthe increased stability of bi- and tetradentate ligands.

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.

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.
