A Framework for Presenting the Modern Atom  James J. Leary and Tadd C. Kippeny
A flow chart is presented that summarizes major empirical and theoretical accomplishments that contributed to the modern view of the atom. A chronology is included to show the time dependence of the various contributions. Suggestions are made about how this chart can be used in a variety of contexts as a framework for discussing science as a process.

The Crucial Role of Kinetic Energy in Interpreting Ionization Energies  Frank Rioux and Roger L. DeKock
The experimental ratio of the ionization energies of H and He is 1.81. The authors show that it is not correct to interpret this ratio using a classical Coulombic potential energy model. Rather a quantum mechanical model is required in which both kinetic and potential energy play a role.

Getting Close with the Instructional Scanning Tunneling Microscope  Carl Steven Rapp
This state-of-the-art instrumentation is making it possible for students to actually view atoms in their own classroom. What is truly amazing, however, is that the ISTM can be set up and atomic resolution images obtained in about an hour.

How does the electron cross the node?  Johnsen, Russell H.; Lloyd, Winston D.
Confusion arises from the assumption that the electron is a particle, when the model that produces an orbital diagram assumes that the electron behaves as a wave.

Atomic orbitals: Limitations and variations  Cohen, Irwin; Bustard, Thomas
The three most widely used methods of arriving at a set of atomic orbitals afford respective hydrogen-like orbitals, self-consistent field orbitals, and various analytical approximations such as the Slater or Morse orbitals, all of which may differ greatly in shape and size from each other.

Tangent-sphere models of molecules. III. Chemical implications of inner-shell electrons  Bent, Henry A.
While a study of atomic core sizes might seem to hold little promise of offering interesting insights into the main body of chemical theory, it is demonstrated here that from such a study emerges a picture of chemical bonding that encompasses as particular cases covalent, ionic, and metallic bonds.
