WebIsotopes are simply specifying the number of neutrons and protons (together called nucleons) in the atom. So, Carbon-12, which has an atomic mass number of 12, has 6 neutrons (12 nucleons - 6 protons = 6 neutrons). Carbon-13, which has an atomic mass number of 13, has 7 neutrons (13 nucleons - 6 protons = 7 neutrons). WebWhen we write the symbol for an atom, we can place its mass number at the top left and its atomic number at the bottom left. You can use these numbers to calculate the number of protons,...
