WebThe number of protons in an isotope atom does not change but the number of neutrons does. The argon atom has about twenty-six isotopes. Such as 29 Ar, 30 Ar, 31 Ar, 32 Ar, … Therefore, a mercury atom has eighty protons and eighty electrons. The number of neutrons in an atom can be determined by the difference between the atomic mass and the number of protons. The difference between the mass number of the mercury atom and the number of protons is one hundred twenty-one.
