• VSEPR - Just used this website for VSEPR.  Very Cool!!  (Except the column headings are a bit misleading - e- pairs should be steric number because if you have a double bond it only counts as 1 for VSEPR.)

Compound Formulas and Nomenclature

• Polyatomic Ion Puzzle Matching Game...this is for Honors level and above.
  However you can purchase the program and have the developer simplify it for regular level:  http://chemistrygeek.com/rainbow/launch.htm

• Electron Configuration Animation Online 
  Posted on the ChemEd-L by Doris R. Kimbrough of the University of Colorado at Denver.
  An Electron Configuration animation from the Okalahoma State University. 
  When you click on the screen, electron arrows are added to the energy level orbital diagram, 
  the element's identification changes and the visual obeys Hund's Rule.

• The Piston - Ideal Gas Law In this series of experiments, you will control the action of a piston in a pressure chamber which is filled with an ideal gas. This experiment is set up so that changes in the state of the gas, e.g. its Temperature, Volume and Pressure, are automatically recorded on the graphical tool.
