How many electrons does a neutral oxygen 16 atom have?
8 electrons
The number of protons and the number of electrons are always the same in an element that is neutral and has no charge. Therefore oxygen has 8 electrons. You will find that the atomic weight of oxygen is about 16.
What is the nuclear charge of an oxygen 16 atom?
+8
The nucleus consisted of both protons and neutrons. It was the neutrons that accounted for the extra mass of the nucleus. Thus, the oxygen nucleus had a charge of +8 but a mass of 16. That was because it was made up of 8 protons and 8 neutrons.
What is the 16 of oxygen?
Oxygen-16 (16O) is a stable isotope of oxygen, having 8 neutrons and 8 protons in its nucleus. It has a mass of 15.99491461956 u. Oxygen-16 is the most abundant isotope of oxygen and accounts for 99.762% of oxygen’s natural abundance….Oxygen-16.

Why the mass number of this atom is 16?
Oxygen has an atomic number of 8 , and the mass number of an atom is the sum of its atomic number plus its neutron number. We got the mass as 16 units, and so it’ll have 16−8=8 neutrons.
Is oxygen 16 naturally occurring?
Naturally occurring oxygen is composed of three stable isotopes, 16O, 17O, and 18O, with 16O being the most abundant (99.762% natural abundance). Depending on the terrestrial source, the standard atomic weight varies within the range of [15.99903, 15.99977] (the conventional value is 15.999).
Why is oxygen 16?
Two isotopes of oxygen. Because protons and neutrons are roughly equal in mass, an isotope’s number is equal to the sum of its protons and neutrons. 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.
Where is oxygen-16 found?
occurs in three isotopes: 16O (99.763 percent), 17O (0.0375 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.
Why is oxygen-16 important?
It has a mass of 15.99491461956 u. Oxygen-16 is the most abundant isotope of oxygen and accounts for 99.762% of oxygen’s natural abundance….Oxygen-16.

Is oxygen-16 naturally occurring?
How many electrons does a neutral oxygen atom have?
A neutral oxygen atom will also contain eight electrons, but it is possible for an oxygen atom to be ionized, in which case it will have more or fewer (up to ten, or down to zero), depending on how it became ionized. Oxygen has several isotopes, and they have different numbers of neutrons.
What is the neutral state of oxygen?
The neutral state of an atom is when it’s net charge is zero; that is, the number of protons equals the numbers of electrons. Oxygen is the eighth element in the periodic table, with the symbol O.
What is the difference between 16 and 18 isotopes of oxygen?
Isotopes are forms of a chemical element that have the same atomic number but differ in mass. 16O 8 protons + 8 neutrons; a “light” oxygen); The relative amounts are expressed as either 18O/16O or δ18O Oxygen – 18 (aka 18O 8 protons + 10 neutrons; a “heavy” oxygen). 16 and 18 are atomic masses of isotopes 16O and 18O.
How many protons are in the isotope 16O?
Oxygen is made up of two isotopes: Oxygen – 16 (also known as. 16O 8 protons + 8 neutrons; a “light” oxygen); The relative amounts are expressed as either 18O/16O or δ18O Oxygen – 18 (aka 18O 8 protons + 10 neutrons; a “heavy” oxygen).
