The terms molecule, compound, and atom can be confusing! Here's an explanation of what a molecule is (and is not) with some examples of common molecules. Answer: Molecules form when two or more atoms form chemical bonds with each other. It doesn't matter if the atoms are the same or are different from each other.ll compounds are molecules; not all molecules are compounds. Single atoms of elements are not molecules. A single oxygen, O, is not a molecule. When oxygen bonds to itself (e.g., O 2, O 3) or to another element (e.g., carbon dioxide or CO 2), molecules are formed.
