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 Genius of Slater's Rules  James L. Reed
With only a few modifications a procedure has been developed that yields the one-electron energies for atoms and ions with a level of detail very well suited for instruction in the structure and properties of atoms. It provides for the computation of very reasonable values for such properties as ionization energies, electron affinities, promotion energies, electronic transitions, and even XPS and ESCA spectra.

Developmental instruction: Part II. Application of the Perry model to general chemistry  Finster, David C.
The Perry scheme offers a framework in which teachers can understand how students make meaning of their world, and specific examples on how instructors need to teach these students so that the students can advance as learners.

The periodicity of electron affinity  Myers, R. Thomas
In general, the values of electron affinity for the elements can be understood in terms of their ground state electron configuration, and the screening (effective nuclear charge) exerted on the added electron by the electrons already present in the neutral atom.

An upward view of the periodic table: Getting to the bottom of it  Guenther, William B.
Develops the 18-group basis of the periodic table; shows that, while the 1-18 designations can give unambiguous information to students, no printed designations are needed for teaching; and shows how to obtain unique, physical group definitions that avoid the problems of conflicting and changeable chemical interpretations.

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.
