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.

Microscale Demonstration of the Paramagnetism of Liquid Oxygen with a Neodymium Magnet Bruce Mattson
When a neodymium magnet is brought near a suspended glass tube containing a small amount of liquid oxygen, the tube is attracted to the magnet, demonstrating oxygen's paramagnetism. In larger quantities the blue color of liquid oxygen is readily observable.

Moving Beyond the Single Center—Ways To Reinforce Molecular Orbital Theory in an Inorganic Course Marion E. Cass and William E. Hollingsworth
Rather than ending the discussion of molecular orbital (MO) theory in an inorganic chemistry course with molecules such as octahedral ML6 or square planar ML4, we suggest moving beyond the single-atom center to include the MO diagram of ethene (C2H4).

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.

Exchange stabilization and the variation of ionization energy in the pn and dn series Blake, Antony B.
This article is concerned with two types of ionizations that are of special importance to chemists. The author's main purpose is to clarify current textbook interpretations of the peculiar decrease in ionization energy following completion of a half-filled p or d shell.
