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.
Chemical reactions occur whenever bonds are formed or broken between molecules. Why certain atoms combine with which other atoms is a complex question which is explained exhaustively by quantum chemistry. The simple version is that atoms bond together electromagnetically based on the properties of their electron shells.cientists combine substances to cause chemical reactions. Oxygen combines with iron in a chemical reaction to form iron oxide, which is more commonly known as rust. Chemists may perform chemical reactions.
