WebElements on The Periodic Table Every chemical element has a specific atomic number, which provides insight into the number of protons present within its nucleus. All isotopes of an element fall under a single cell on … 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).
