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.

Electron Affinities of the Alkaline Earth Metals and the Sign Convention for Electron Affinity John C. Wheeler
It has been known since 1987, both theoretically and experimentally, that the ion Ca- is stable. It is now certain that Sr-, Ba-, and Ra- are also stable, and accurate values for the electron affinities of Ca-, Sr-, and Ba- have been determined. Recommended values for these electron affinities, in the units commonly employed in introductory texts and with the sign convention used here, are 2.37, 5.03, and 13.95 kJ/mol for Ca, Sr, and Ba, respectively.

The correct interpretation of Hund's rule as applied to "uncoupled states" orbital diagrams Campbell, Mark L.
The application of Hund's rule by general chemistry students is appropriate as long as Hund's rule is interpreted correctly.

Chemistry according to ROF (Fee, Richard) Radcliffe, George; Mackenzie, Norma N.
Two reviews on a software package that consists of 68 programs on 17 disks plus an administrative disk geared toward acquainting students with fundamental chemistry content. For instance, acids and bases, significant figures, electron configuration, chemical structures, bonding, phases, and more.

Why teach the electron configuration of the elements are we do? Millikan, Roger C.
Out of 106 elements in the table of electron configurations, there are 29 special cases - rules that only work 73% of the time seem hardly worth teaching.

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.
