Mercury has an atomic number of 80 and an atomic mass of 200. Mercury has number of protons, number of electrons and number of neutrons. Mercury200, Mercury201 and Mercury202, are isotopes, which means they contain the same number of , but different number of . If mercury loses two electrons, it will gain two charges.
