During a chemical reaction, the number of atoms **stays the same**. This is due to the law of conservation of mass, which states that matter cannot be created or destroyed in a closed system. Thus, the total number of atoms before the reaction is equal to the total number of atoms after the reaction, even though they may rearrange to form new substances.
