Atoms of a given element are identical (meaning they have the same mass and properties). Atoms retain their identity in all chemical reactions. This is basically the Law of Conservation of Matter, stating that an equal amount of mass exists before and after a reaction. But, all atoms are not the same. You know that the number of protons in an atom determines what element you have. For instance hydrogen has one proton, carbon has six.
