What is the difference between a compound and a molecule? A compound is a substance that is composed from two or more different elements. Water (H 2 O), table salt (NaCl), carbon dioxide (CO 2), methane (CH 4) and chlorophyll (C 55 H 72 O 5 N 4 Mg) are a few examples of compounds. They are compounds because they each contain more than one kind of element.
