Determine the number of neutrons
WebSep 9, 2024 · This chemistry video tutorial explains how to calculate the number of protons, neutrons, and electrons in an atom or in an ion. It also explains the difference … 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).
