Thermochromism: Mercury(II) Iodide When red-orange Mercury(II) Iodide (HgI2) is heated, it undergoes a phase transition at 126oC to a pale yellow form. As the heated sample cools, it gradually returns to the original red-orange color.
A New "Bottom-Up" Framework for Teaching Chemical BondingTami Levy Nahum, Rachel Mamlok-Naaman, Avi Hofstein, and Leeor Kronik This article presents a general framework for bonding that can be presented at different levels of sophistication depending on the student's level and needs. The pedagogical strategy for teaching this model is a "bottom-up" one, starting with basic principles and ending with specific properties. Levy Nahum, Tami; Mamlok-Naaman, Rachel; Hofstein, Avi; Kronik, Leeor. J. Chem. Educ.2008, 85, 1680.

Ionic BlocksRichard S. Sevcik, Rex Gamble, Elizabet Martinez, Linda D. Schultz, and Susan V. Alexander "Ionic Blocks" is a teaching tool designed to help middle school students visualize the concepts of ions, ionic compounds, and stoichiometry. It can also assist high school students in reviewing their subject mastery. Sevcik, Richard S.; Gamble, Rex; Martinez, Elizabet; Schultz, Linda D.; Alexander, Susan V. J. Chem. Educ.2008, 85, 1631.
