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.
The strength of a bond is inversely proportional to the strength of its chemical potential energy.
