How many protons electrons and neutrons does oxygen have?

Answer 1

Oxygen has 8 protons as its atomic number is 8. It therefore has 8 electrons also for charge neutrality. The number of neutrons depends on the isotope. O-15 isotope will have 7 neutrons, O-16 isotope will have 8 neutrons.

(Note: Mass number = Number of protons + number of neutrons)

Answer 2

An oxygen atom has 8 protons and 8 neutrons in the nucleus, which is orbited by 8 electrons. However there are three stable isotopes of oxygen: 16O, 17O and 18O. An isotope is an element with the same number of protons in the nucleus but a different number of neutrons. Over 99% of oxygen atoms are 16O. This has 8 protons and 8 neutrons. 17O has 8 protons and 9 neutrons. 18O has 8 protons and 10 neutrons.

Answer 3

Oxygen has 8 protons, 8 electrons, and 8 neutrons.

Look at the Periodic Table of the elements. The atomic number is same value as the protons and electrons. Round the Atomic Mass to a whole number then go mass-protons=neutrons.

Answer 4

It depends on the isotope. All neutral atoms of oxygen have 8 protons and 8 electrons. The atoms of the different isotopes of any given element differ only in the number of neutrons. Atoms of the isotope oxygen-16 also have 8 neutrons, atoms of the isotope oxygen-17 have 9 neutrons, and atoms of the isotope of oxygen-18 have 10 neutrons. Oxygen-16 is by far the most abundant isotope, at 99.76%. So the vast majority of oxygen atoms will have 8 protons, 8 electrons, and 8 neutrons.

Answer 5

Oxygen has 8 protons, 8 (or sometimes 7) neutrons and 8 electrons.

Answer 6

Oxygen's atomic number is 8. Thus, neutral oxygen has 8 protons and 8 electrons per atom. 16O is oxygen's most common isotope, and it has 16 - 8 = 8 neutrons.

Answer 7

Oxygen has 8 protons, 8 electrons, and usually 8 neutrons (in the stable isotope Oxygen-16).

Answer 8

In it's natural state, it has 8 of each.
