Sauerstoff1816O
Sauerstoff1816O, commonly known as oxygen-18 or 18O, is a stable isotope of oxygen. It contains eight protons, eight neutrons, and eight electrons, giving it an atomic mass of approximately 18 atomic mass units. This isotope is one of the three naturally occurring isotopes of oxygen, the others being oxygen-16 (16O) and oxygen-17 (17O).
Oxygen-18 is less abundant than oxygen-16, making up about 0.204% of the total oxygen content on Earth.
In the field of paleoclimatology, the ratio of oxygen-18 to oxygen-16 in ice cores is used to
Oxygen-18 is also used in various scientific and medical applications. In medicine, it is used in positron
