Mistake of Having Students Be Mendeleev for Just a Day  Brett Criswell
This article discusses several conceptual features underlying a genuine understanding of the periodic table and describes a set of activities focused on promoting such awareness in students using the FERA (focus, explore, reflect, and apply) learning cycle model.

Why Gold and Copper Are Colored but Silver Is Not  Ariel H. Guerrero, Héctor J. Fasoli, and José Luis Costa
Interpretation of the yellow color of gold based on an adequate external electronic configuration (s1d10/s2d9) and s and d sublevels close enough to allow transition between them to proceed significantly.

Periodic properties in a family of common semiconductors: Experiments with light emitting diodes  Lisensky, George C.; Penn, Rona; Geselbracht, Margret J.; Ellis, Arthur B.
The prevalence of LED's and their low cost make LED's ideal for classroom demonstrations or laboratory experiments showing the connection between periodic trends in physical/chemical properties and a common high tech device.

A simple laboratory experiment illustrating the relative nature of atomic weights  Huff, Randolph B.; Evans, David W.
The concept of atomic weight scale remains a source of confusion for beginning chemistry students. This paper proposes a simple lab experience that could help students better understand this idea.

Regularities among the representative elements: The "paired electron rule"  Condon, F. E.
If the oxidation states characteristic of various groups are correlated in terms of electron subshells, they become reasonable and logical rather than mere facts to be memorized.
