This is because they are all made up of different types of molecules. Molecules are not only made up of different types of atoms but also different ratios. Like in the water example above, a water molecule has 2 hydrogen atoms and 1 oxygen atom.This is written as H 2 O.olecules are not only made up of different types of atoms but also different ratios.
