Best Answer

When two or more atoms combine, the product is a molecule.

Examples

two oxygen atoms combine to form a molecule of oxygen O2

two hydrogen atoms and an oxygen atom combine to form a molecule of water H2O

If there are two or more elements in the molecule, the substance is a compound. Water is a compound; oxygen is not.
