8 1 is called the mass defect. Its interpretation can be found in Einstein's mass-energy eq formed, some of the mass of its constituent protons and the neutrons gets converted i the nucleus together. 16 The most common oxygen isotope is 0, but the rarer isotopes O and 0 of this element also exist in nature. These less common isotopes are stable, and measurements of their abundances have proved crucial in many fields of scientific research. For example, in climate research studies, the ratio of O to 0 measured in natural Part C 8. waters, as well as in polar ice, can provide useful information on the precipitiation history in a given area. This is because water containing O evaporates less readily, and condenses more easily as precipitation, than water containing 0.
