Actually element do not always consist of atoms but also of molecules.
For example Oxygen consists of molecules made of two atoms of Oxygen.
The main difference is the elements molecules consist of all atoms
with the same atomic number (or of the same kind) while a compost
molecule can be done   with two or more different atoms
