A molecule is two or more atoms chemically joined together. If at least two different elements make up the molecule, it is called a compound. For example, hydrogen gas (H2) and water (H2O) are molecules, but water is also a compound because it is made up of hydrogen and oxygen.f at least two different elements make up the molecule, it is called a compound.
