Probing the Orbital Energy of an Electron in an Atom James L. Bills This article answers an appeal for simple theoretical interpretations of atomic properties. A theoretical snapshot of an atom, showing the screened nuclear charge and the electron to be ionized at its radius of zero kinetic energy, enables anyone to approximate its ionization energy.

Are Some Elements More Equal Than Others? Ronald L. Rich Presents a new periodic chart with 18 columns but no interruptions of atomic numbers at Lanthanum or Actinum, and no de-emphasis of elements 57-71 or 89-103 by seeming to make footnotes of them. It shows some elements more than once in order to illuminate multiple relationships in chemical behavior. Rich, Ronald L. J. Chem. Educ. 2005, 82, 1761.

The Ubiquitous Metaphors of Chemistry Teaching Herbert Beall The understanding and the confusion resulting from any scientific metaphor thus have to be considered when it is used. For example, a common chemical metaphor for the electron distribution about an atom is a cloud. Some of the entailments of this metaphor are apt, such as the diffuse nature of a cloud. Others, such as the ability of a cloud to evaporate, are not appropriate. Beall, Herbert. J. Chem. Educ. 1999, 76, 366.

How Good Is the Quantum Mechanical Explanation of the Periodic System? Eric R. Scerri The use of quantum mechanics, or more specifically, orbitals and electronic configurations in teaching general chemistry is now such a widespread trend that it would be utterly futile to try to reverse it. Moreover, orbitals and configurations have been extremely useful in providing a theoretical framework for the unification of a multitude of chemical facts. Scerri, Eric R. J. Chem.

Experimental 4s and 3d Energies in Atomic Ground States James L. Bills A new definition is given for the effective charge Zf. HF orbital energies e4s and e3d are used in concert with I4s and I3d to answer four questions: Why does the 4s sublevel fill before 3d? Why is ionization easier for 4s than 3d? When 4s23dn has e3d < e4s, why doesn't 4s23dn -> 4s13dn+1? Why are Cr and Cu each 4s13dn+1 instead of 4s23dn? Bills, James L. J. Chem. Educ. 1998, 75, 589.
