Oxygen (chemical symbol O) has three naturally occurring isotopes: O, O, and O, where the 16, 17 and 18 refer to the atomic mass. The most abundant is O, with a small percentage of O and an even smaller percentage of O. Oxygen isotope analysis considers only the ratio of O to O present in a sample. The calculated ratio of the masses of each present in the sample is then compared to a standar… Web12 nov. 2012 · However there are three stable isotopes of oxygen: 16O, 17O and 18O.
