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
.
What is the use of oxygen 17?
Oxygen-17 (
17
O) is now being used for
diagnostic applications and medical research to create a new generation of NMR Images
. New developments with
17
O enhance the quality of information about living tissue to improve the practice of medicine in the fields of cardiology and neurology among others.
Does oxygen 17 and oxygen 18 have the same mass?
Which statement is true about oxygen-17 and oxygen-18? They do not have the same number of protons.
Their atoms have an identical mass
. They are isotopes of oxygen.
What is oxygen 18 water used for?
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 do oxygen 17 and oxygen 18 have in common?
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
.
How does the overall charge of oxygen 16 compared to the overall charge of oxygen 17 and 18?
The positive charge of the protons in the nucleus is balanced by the negative charge of the electrons. What is the difference between atoms of oxygen-16 and oxygen-17?
Each oxygen-17 atom has one more neutron than each oxygen-16 atom
.
What is the name of oxygen-17?
| General | Names oxygen-17, O-17 | Protons 8 | Neutrons 9 | Nuclide data |
|---|
Where is oxygen-17 found?
Quaternary research
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-17?
An
English chemist, Joseph Priestley
, independently discovered oxygen in 1774 by the thermal decomposition of mercuric oxide and published his findings the same year, three years before Scheele published.
Why is O 18 considered heavy?
Since it is lighter than
18
O,
16
O evaporates first, so in warm, tropical areas,
the ocean is high in
18
O. Additionally, as water vapor condenses to form rain, water droplets rich in
18
O precipitate first because it is heavier than
16
O.
What is the symbol for oxygen 18?
| General | Symbol 18 O | Names oxygen-18, O-18, Ω Heavy Oxygen | Protons 8 | Neutrons 10 |
|---|
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 is the abundance of oxygen-18?

Is oxygen-16 stable or unstable?
Unsourced material may be challenged and removed. Oxygen-16 (
16
O) is a
stable isotope of oxygen
, having 8 neutrons and 8 protons in its nucleus. It has a mass of 15.99491461956 u.
What are the 3 isotopes of oxygen?
The element oxygen has three stable isotopes:
16
O,
17
O, and
18
O
