    An atom is an electrically neutral particle. It has a nucleus composed of heavy positively charged protons and neutral neutrons. Around the nucleus orbit negatively charged electrons. Since the atom is electrically neutral the number of protons equal the number of electrons.

    An ion is an atom that some electrons has either been added or removed, hence providing the particle a net ...
