WebOxygen Oxygen ‘s main isotope is oxygen-16. The other most common isotopes are oxygen-17 and oxygen-18. The isotopes of oxygen are often used to study the history of the climate. Using ice cores and water samples the ratio of the different isotopes of oxygen in these samples tells scientists about previous climates.
There are three known stable isotopes of oxygen (8O): O , O , and O . Radioactive isotopes ranging from O to O have also been characterized, all short-lived. The longest-lived radioisotope is O with a half-life of 122.266(43) s, while the shortest-lived isotope is O with a half-life of 198(12) yoctoseconds.
