Explanation:

Molecules are particles of elements or compounds that are made of more than one atoms. Molecules of an element are made up of similar atoms. For example, Oxygen molecule, O₂, has two oxygen atoms and chlorine molecule, Cl₂, has two chlorine atoms.Molecules of a compound are made up of different types of atoms, for example, a water molecule, H₂O is made up of two hydrogen atoms and one oxygen atom.Molecules of a compound have similar properties that are similar to that of the compound. The properties of a molecule of a compound are different from those of an individual atom.
