Which statement is true about oxygen 17 and oxygen 18
What’s the difference between oxygen-17 and oxygen 18?
Chemical elements are found in different versions, called isotopes. Isotopes are elements that contain the same amount of protons, but differ in the number of neutrons in their nuclei. … Therefore, oxygen 16 has 8 protons and 8 neutrons, oxygen 17 has 8 protons and 9 neutrons, and oxygen 18 has 8 protons and 10 neutrons.
Do oxygen-17 and oxygen 18 have the same mass?
Oxygen 17 has an atomic mass of 17 and Oxygen 18 has an atomic mass of 18. Now, they both have 8 protons, so are isotopes of the same element with different atomic mass. O17 and O18 are isotopes of oxygen!
Do oxygen-17 and oxygen 18 have the same number of neutrons?
Subtract the number of protons (8) from the mass numbers to determine the number of neutrons in the different isotopes. So oxygen-16 has 8 neutrons, oxygen-17 has 9 neutrons, and oxygen-18 has 10 neutrons.
What particle is the difference between oxygen-16 and oxygen-17?
Oxygen-16 has one less neutron than oxygen-17. To find the number of neutrons, just subtract the number of protons from the mass number.
How do two isotopes of oxygen oxygen-16 and oxygen-18 differ from each other in structure?
How do 2 isotopes of oxygen–oxygen-16 and oxygen-18–differ from each other in structure? … Oxygen-18 has 2 more neutrons than oxygen-16. The chemical properties of these 2 atoms are similar because they’re isotopes, with the same number of protons.
Is oxygen-18 stable or unstable?
While most oxgen atoms have a mass of 16 (8 protons and 8 neutrons), a small number of oxygen atoms have a mass of 18 (8 protons and 10 neutrons). Both of these isotopes are stable; they do not undergo radioactive decay. Water molecules (H2O) in the ocean may contain either isotope, oxygen 16 or oxygen 18.
What does the number 17 in the name oxygen-17 represent?
Oxygen-17 (17O) is a low-abundance, natural, stable isotope of oxygen (0.0373% in seawater; approximately twice as abundant as deuterium).

What is the use of oxygen-17?
Oxygen-17 (17O) is now being used for diagnostic applications and medical research to create a new generation of NMR Images. New developments with 17O enhance the quality of information about living tissue to improve the practice of medicine in the fields of cardiology and neurology among others.
What is the protons of oxygen-18?
All oxygen atoms have 8 protons, but the nucleus might contain 8, 9, or 10 neutrons. “Light” oxygen-16, with 8 protons and 8 neutrons, is the most common isotope found in nature, followed by much lesser amounts of “heavy” oxygen-18, with 8 protons and 10 neutrons.
What is oxygen-18 water used for?
O-18 is used as a tracer in many hydrologic studies. It is most often used as a component in a mixing-model and hydrograph separation, as O-18 acts conservatively and is applied naturally and uniformly over broad areas. O-18 can be used when different sources (old water/new water) have different isotopic values.
Who discovered oxygen-17?
Oxygen was discovered about 1772 by a Swedish chemist, Carl Wilhelm Scheele, who obtained it by heating potassium nitrate, mercuric oxide, and many other substances.
What is the neutrons of oxygen-17?
# neutrons = mass # – #protons. So, in oxygen-17, # neutrons = 17 – 8 or 9. Oxygen-17 has 8 protons, 8 electrons, and 9 neutrons.
What is oxygen-18 called?
oxygen-18, O-18, Ω Heavy Oxygen.
How do you write oxygen-18?
How is oxygen-18 formed?
Oxygen is composed of 8 protons, and in its most common form with 8 neutrons, giving it an atomic weight of 16 (16O) — this is know as a “light” oxygen. It is called “light” because a small fraction of oxygen atoms have 2 extra neutrons and a resulting atomic weight of 18 (18O), which is then known as “heavy” oxygen.
Where is oxygen-18 found?
0375 percent), and 18O (0.1995 percent). Oxygen is found in all organisms and many minerals, including the aragonite and calcite that make up the shells of marine microfossils such as foraminifera.
Who discovered oxygen-18?
The 18th century scientist Antoine Lavoisier disproved the existence of phlogiston and helped to form the basis of modern chemistry using Joseph Priestley’s discovery of oxygen. Pneumatic trough and other equipment used by Joseph Priestley in his experiments on oxygen and other gases.
Is oxygen-17 stable or unstable?
Oxygen-17 atom is the stable isotope of oxygen with relative atomic mass 16.999131. The least abundant (0.038 atom percent) isotope of naturally occurring oxygen.
What is the use of oxygen-18 isotope?
Oxygen-18 in the water or gaseous form serves as a source for short-lived positron-emitting isotope fluorine-18, which allows tracking the processes of cerebral blood flow, glucose metabolism in the central nervous and cardiovascular systems, evaluating the impact of drugs on neuroreceptors.
What is the charge of oxygen-18?
