Connecting Solubility, Equilibrium, and Periodicity in a Green, Inquiry Experiment for the General Chemistry Laboratory Kristen L. Cacciatore, Jose Amado, Jason J. Evans, and Hannah Sevian Presents a novel first-year chemistry experiment that asks students to replicate procedures described in sample lab reports that lack essential information. This structure is designed to promote students' experimental design and data analysis skills as well as their understanding of the importance and essential qualities of written and verbal communication between scientists. Cacciatore, Kristen L.; Amado, Jose; Evans, Jason J.; Sevian, Hannah. J. Chem. Educ. 2008, 85, 251.

The Different Periodic Tables of Dmitrii Mendeleev Michael Laing Between 1869 and 1905 the Russian chemist Dmitrii Mendeleev published several tables with different arrangements of the chemical elements. Four of these are compared with periodic tables by Russian scientists from 1934 and 1969. Laing, Michael. J. Chem. Educ. 2008, 85, 63.

News from the Periodic Table: An Introduction to "Periodicity Symbols, Tables, and Models for Higher-Order Valency and Donor–Acceptor Kinships" Henry A. Bent and Frank Weinhold Proposes that alternative display topologies such as a 2D "left-step" or "step-pyramid" table or 3D "periodic towers" can supplement or supplant the standard periodic table by better emphasizing higher-order patterns of chemical association and reactivity, rather than the physical resemblances of standard-state elemental substances.

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.

Using History to Teach Scientific Method: The Role of Errors Carmen J. Giunta This paper lists five kinds of error with examples of each from the development of chemistry in the 18th and 19th centuries: erroneous theories (phlogiston), seeing a new phenomenon everywhere one seeks it (Lavoisier and the decomposition of water), theories erroneous in detail but nonetheless fruitful (Dalton's atomic theory), rejection of correct theories (Avogadro's hypothesis), and incoherent insights (J. A. R. Newlands' classification of the elements). Giunta, Carmen J. J. Chem. Educ. 2001, 78, 623.

Ionization Energies, Parallel Spins, and the Stability of Half-Filled Shells Peter Cann Three methods for explaining the decrease in first ionization energies between group V and group VI elements are described and commented upon. The quantum mechanical origin of the unhelpful concept of half-shell stability is explained in terms of exchange energy, for which the alternative term parallel spin avoidance factor is suggested. It is recommended that for pre-university students the simplest explanation, in terms of Coulombic repulsion between two electrons occupying the same orbital, is adopted: it involves fewer difficult concepts than the other explanations and its predictions are no less accurate.

Principles of electronegativity Part I. General nature Sanderson, R. T. The concept of electronegativity has been modified, expanded, and debated. The concept can be used to help students gain valuable insights and understanding of the cause-and-effect relationship between atomic structure and compound properties. This is the first in a series of articles that explores the important concept of electronegativity. Sanderson, R. T. J. Chem. Educ. 1988, 65, 112.

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.
