When a chemical reaction does not occur, what happens to the atoms of the two substances? 

1 answer

When a chemical reaction does not occur between two substances, the atoms of those substances remain unchanged and retain their original arrangements and properties. The atoms might be physically mixed together, but they do not undergo any transformation into new substances. This means that the chemical bonds that hold the atoms together in their respective molecules or compounds remain intact, and no new chemical bonds are formed. As a result, the individual substances maintain their identity and characteristics, and no new products are generated.
