Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.

Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.

	Overview and Learning Objectives Students manipulate increasingly strong bonds, from hydrogen-hydrogen to chlorine-chlorine, to H and Cl, watching the change in potential energy. Finally they make predictions about the likelihood of bond breaking starting with Cl2 and H2. Students will understand that the strength of a bond is inversely proportional to the strength of its chemical potential energy. return to top
