How do you know which isotope is abundant
WebIsotope Pennies Lab. Introduction: Isotopes are atoms, of a given element, that have the same number of protons, but a different number of neutrons in the nucleus. For example: C-12 and C-14 are carbon isotopes. They each have 6 protons (atomic # = 6), but one has 6 neutrons while the other has 8 neutrons. WebView Answer. Define isotope using the terms mass number, atomic number, number of protons, number of neutrons, and number of electrons. View Answer. Naturally occurring iodine has an atomic mass of 126.9045 amu.
