Isotopes of oxygen - Wikipedia
There are three known stable isotopes of oxygen (8 O): 16 O, 17 O, and 18 O. Radioactive isotopes ranging from 11 O to 28 O have also been characterized, all short-lived. The longest-lived radioisotope is 15 O with a half-life of 122.266(43) s, while the …
Oxygen Isotopes - List and Properties - ChemLin
List, data and properties of all known isotopes of Oxygen. Three stable isotopes of the chemical element oxygen occur in nature, of which the nuclide 16 O is the most common with a proportion of over 99.7%: Due to fluctuations in the isotope ratio of natural oxygen, the atomic mass varies in the range from 15.99903 to 15.99977 u.
4.7: Isotopes and Mass Numbers - Chemistry LibreTexts
2024年8月26日 · Isotopes of elements are designated by their mass number. Oxygen atoms with a mass number of 16 are called oxygen-16, or O-16, while oxygen atoms with a mass number of 17 are called oxygen-17, or O-17, and oxygen atoms with a mass number of 18 are called oxygen-18, or O-18.
Oxygen Isotopes - SpringerLink
2017年11月14日 · Natural oxygen is a mixture of three stable isotopes 16 O, 17 O, and 18 O. Mass-dependent and mass-independent isotope fractionations are observed in nature. Oxygen isotopes are useful tracers to determine the origin of natural materials and molecule, and cosmochemical and geochemical processes.
Paleoclimatology: The Oxygen Balance - NASA Earth Observatory
Oxygen comes in heavy and light varieties, or isotopes, which are useful for paleoclimate research. Like all elements, oxygen is made up of a nucleus of protons and neutrons, surrounded by a cloud of electrons. All oxygen atoms have 8 protons, but the nucleus might contain 8, …
Oxygen Isotopes - SpringerLink
2016年1月1日 · Stable oxygen isotope ratios are widely measured in archaeologically and paleontologically recovered bones and teeth as measures of climate change, geographic provenance, migration, and cultural behavior.
Oxygen group element - Isotopes, Atomic Mass, Properties
Natural oxygen is a mixture of three stable isotopes: oxygen-16 (99.759 percent), oxygen-17 (0.037 percent), and oxygen-18 (0.204 percent). Several artificially prepared radioactive isotopes are known. The longest-lived, oxygen-15 (124-second half-life), has been used to study respiration in mammals.
Compare two isotopes of oxygen in ice cores, coral reefs, and sediments. Atoms of all matter on Earth are made up of a nucleus and electrons. Isotopes are forms of a chemical element that have the same atomic number but differ in mass. Oxygen - 18 (aka 18O 8 protons + 10 neutrons; a “heavy” oxygen).
Oxygen Isotopes - SpringerLink
Oxygen has three stable isotopes with atomic mass numbers of 16, 17, and 18 (16 O, 17 O and 18 O), which occur naturally in relative proportions of 99.76%, 0.04%, and 0.2%, respectively.
