What happens to a chemical bond during a chemical reaction? Chemical reactions always involve changes in the chemical bonds  that join atoms in compounds. At least one chemical bond is broken  or formed during a chemical reaction.
All chemical bonds posses potential energy. In a chemical reaction this energy is changed when old bonds are broken and new bonds are formed. Chemical changes are different from physical changes. When a physical change occurs there is no breaking and forming of bonds. There are certain things that will help us identify if a chemical reaction has taken place. We call these evidences of chemical reactions. Light is given off: Potential energy in valance electrons is released in the form of light.
