The main thing I want to tell you is that he arranged these elements in the increasing order of their ATOMIC MASS. Now, let me recall to you the atomic mass of lithium, sodium and potassium. 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).
