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.

Trends in Ionization Energy of Transition-Metal Elements Paul S. Matsumoto Examines why, as the number of protons increase along a row in the periodic table, the first ionization energies of the transition-metal elements are relatively steady, but that for the main-group elements increases. Matsumoto, Paul S. J. Chem. Educ. 2005, 82, 1660.

Predicting the Atomic Weights of the Trans-Lawrencium Elements: A Novel Application of Dobereiner's Triads Sami A. Ibrahim Dobereiner's concept of triads remain useful for predicting the properties of the super-heavy elements (113118) and for providing reasonable estimates of the atomic weights of all 16 trans-lawrencium elements.

A Living Periodic Table James L. Marshall A complete "living" periodic table of samples of all the elements through uranium is described. In many instances a sample of an element is accompanied by a direct commercial application. This periodic table is very helpful in enabling the student to gain a hands-on understanding of the true nature of the elements--as opposed to the more usual compilation of mere abstract data.

The periodic table: The 6d-5f mixed transition group Coryell, Charles D. With relatively few modifications, the Bohr-type periodic table presented by Glocker and Popov can be made to reflect more instructively the rather complex relationships obtained in the neighborhood of the 4f or gadolinium transition group and, more importantly, in the 6d-5f sequence extending from actinium through the region of uranium and the synthetic earths to element 103. Coryell, Charles D. J. Chem. Educ. 1952, 29, 62.
