Best Answer

The ratio of oxygen isotopes 16O and 18O is used in studies of climate and paleoclimate. This ratio can indicate past temperatures, precipitation levels, and ice volume, providing insights into Earth's climate history.

What correctly compares the oxygen isotopes 16O and 18O?

16O has 8 neutrons, whereas 18O has 10 neutrons.


How many stable isotopes does oxygen have-?

Oxygen consists of three stable isotopes: 16O, 17O, and 18O


Do Oxygen-17 and oxygen-18 have different number of protons?

No, 17O and 18O have differing numbers of neutrons, which make them isotopes of oxygen, along with 16O.


What are the 3 atoms of oxygen?

The three stable atomic isotopes of Oxygen are 16O, 17O, 18O, with 8, 9, and 10 neutrons respectively. In addition 17 radioactive isotopes have been described.


Is O radioactive?

If you mean oxygen: like most elements, it has both stable isotopes, and unstable (i.e., radioactive) isotopes. 16O, 17O and 18O are stable; the unstable (radioactive) isotopes include 15O and 14O.


What is the correct formula for elemental oxygen?

The correct formula for elemental oxygen is O2, indicating that oxygen exists as a diatomic molecule with two oxygen atoms bonded together.


Three example of element that exhibit isotope and their isotopes?

Hydrogen has three isotopes: protium (1H), deuterium (2H), and tritium (3H). Carbon has two stable isotopes: carbon-12 (12C) and carbon-13 (13C), along with a radioactive isotope, carbon-14 (14C). Oxygen has three isotopes: oxygen-16 (16O), oxygen-17 (17O), and oxygen-18 (18O).


How did oxygen exist?

Oxygen is a natural element, and is produced inside a star by fusion processes, beginning with hydrogen - helium and so on. It is the third most common element by mass in our Milky Way galaxy, after hydrogen and helium. There are three common isotopes, 16O, 17O, and 18O, with 16O being by far the most common (>99%). There are another dozen minor isotopes, mostly radioactive with short half-lives. Some 18O is generated by the capture of a helium nucleus by a nitrogen atom. This isotope is useful, as being more massive, it occurs more commonly when the atmosphere warms. The 18O/16O ratio is used as a measure of paleo (ancient) climate, for the oxygen ratio is preserved in ancient ice, and other oxygen-containing substances.


Oxygen in the air is made up of how many atoms?

Oxygen in the air is typically diatomic, meaning it consists of 2 atoms of oxygen chemically bonded together to form O2.


What is the most abundant isotope of oxygen?

There is only one abundant isotope of fluorine and that is 19FFluorine-19 is the most common isotope, its abundance is classed as 100% because no other Fluorine isotopes exist in significant quantities. It is also the only stable Fluorine isotope.


The atomic number of oxygen is 8 therefore oxygen atoms always contain 8 neutrons?

Incorrect. The number of neutrons in an oxygen atom can vary as oxygen has different isotopes with varying numbers of neutrons. The most common isotope of oxygen, oxygen-16, has 8 neutrons, but there are also oxygen isotopes with 9 or 10 neutrons.


Are there any different isotopes of oxygen that are harmful or useful?

Isotopes of oxygen have many beneficial uses such as the following examples. Compressed oxygen is usually made of 16O. Rarest of all the oxygen isotopes, 17O is often used in spectroscopy. It is useful in magnetic resonance experiments, as well as in the study of oxygen and water interactions. Positron Emission Tomography, more widely known as medical imaging, has made the demand for 18O increase world-wide. 18O is also used in the study enzymatic and geochemical reactions, vibrational spectroscopy, as well as insight into chemical reactions and transition states. P.S. I got most of this information off the net, so I'm not sure how accurate this is.
