They can join up with atoms of the same element or with atoms of different elements. Substances whose molecules contain different types of atom are called compounds.Chemical reactions can CHANGE MOLECULES and when this happens, new molecules and therefore new compounds are formed.n a covalent bond, electrons are shared between two atoms. When two oxygen atoms bond together to form an oxygen molecule, they share four electrons â two from each oxygen atom. Other examples of covalent bonding are water (H 2 O), and carbon dioxide (CO 2).
