How many key isotopes does oxygen have
Web29 mrt. 2024 · Oxygen has seventeen known isotopes with atomic masses ranging from 12.03 u to 28.06 u. Three are stable, 16 O, 17O, and 18O, of which 16 O is the most abundant (over 99.7%). The radioisotopes all have half-lives of less than three minutes. WebOxygen-Isotope Data In your prelab, you have learned how the concentration of 18O in water and sediment is represented as δ18O values with units of per mil (parts per thousand, or ‰). Average ocean water is assigned a value of 0‰, and is the standard against which variations in 18O/16O are measured and reported. The process of fractionation
