Stable isotopes are variants of atoms that differ in mass but do not decay over time, that is, they are not radioactive. The element oxygen (O) is found in three naturally occurring stable isotopes, 18 O, 17 O, and 16 O. The nucleus of each of these oxygen isotopes contains eight protons and either eight, nine, or ten ...
