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.

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. Bent, Henry A.; Weinhold, Frank. J. Chem. Educ. 2007, 84, 1145.

Factors That Influence Relative Acid Strength in Water: A Simple Model Michael J. Moran The pKa's of diverse aqueous acids HA correlate well with the sum of two gas-phase properties: the HA bond-dissociation enthalpy and the electron affinity of the A radical. It is suggested that rather than bond strength alone or bond polarity, the sum of the enthalpies of these two steps is a fairly good indicator of relative acidity. Moran, Michael J. J. Chem.

Tangent-sphere models of molecules. III. Chemical implications of inner-shell electrons Bent, Henry A. While a study of atomic core sizes might seem to hold little promise of offering interesting insights into the main body of chemical theory, it is demonstrated here that from such a study emerges a picture of chemical bonding that encompasses as particular cases covalent, ionic, and metallic bonds.
