Reactants and Products in Chemical Reactions. In a chemical reaction, substances (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products. You canât change one element into another in a chemical reaction â that happens in nuclear reactions.
The atoms in the products come from the atoms in the reactants. In a chemical reaction, bonds between atoms in the reactants are broken and the atoms rearrange and form new bonds to make the products. Note: Leave this equation projected throughout the activity in the Explore section of this lesson.
