During a chemical reaction, the number of atoms:

1. **stays the same.**

This is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Therefore, the total number of atoms before and after the reaction remains constant, even though they may be rearranged to form different molecules.
