C.2.2 Determine the number of protons, neutrons, and electrons in isotopes and calculate the average atomic mass from isotopic abundance data. Protons – an elementary particle that is identical with the nucleus of the hydrogen atom, that with the neutron is a constituent of all other atomic nuclei, that carries a positive charge numerically equal to the charge of an electron Neutron – an uncharged elementary particle that has a mass nearly equal to that of the proton and is present in all known atomic nuclei except the hydrogen nucleus Electron – a very small particle of matter that has a negative charge of electricity and that travels around the nucleus of an atom Isotopes – any of two or more species of of a chemical element with the same atomic number and nearly identical chemical behavior but with differing atomic mass or mass number and different physical properties Average atomic mass – sum of the masse of its isotopes, each multiplied by the natural abundance of each Isotopic abundance data – relative number of atoms of different isotopes of one chemical element usually expressed as a percentage of all the long – lived isotopes of that element.
