During a chemical reaction, such as the reaction between iron (Fe) and oxygen (O2) to form iron oxide (rust), the atoms of Fe and O2 are rearranged. This means that the atoms are not lost or gaining mass, nor do they maintain their original properties; rather, they form new substances with different properties.

So, the correct response is:

They are rearranged.
