How many neutrons does oxygen have?

Answer 1

The simple answer is 8 neutrons. But this depends on which oxygen isotope you are talking about. Oxygen-16, the most abundant oxygen isotope, has 8 neutrons.

Answer 2

Not all oxygen atoms have the same number of neutrons. However, the very large majority have 7 neutrons (some have slightly more or less than that).

Number of neutrons = Atomic Mass of an isotope - atomic number (number of protons) The most important stable isotope of oxygen is 16O (99.76 % in the mixture of natural oxygen isotopes); this isotope has 8 neutrons.

Answer 3

Normally, 8.

But, different isotopes, an element with a different numbers of neutrons than usual, have different numbers of neutrons.

The 3 isotopes of oxygen are oxygen-16, the most common, oxygen-18, the second most common, and oxygen-17, the least common. 16 has 8 neutrons, 18 has 10, and 17 has nine.

Answer 4

to get the amount of neutrons in an atom, you have to subtract the atomic mass- in this case 16- by the number of protons, in other words the atomic number, which is 8. as an answer you get a total of 8 neutrons in an oxygen atom.

Answer 5

16

There are 8 protons (so 8 is the atomic number), + 8 neutrons (so 16 is the atomic mass)

Answer 6

Oxygen is one of the most important elements on the periodic table as it is what humans breathe in order to survive. There are eight neutrons in oxygen,

Answer 7

Oxygen has eight neutrons.

Oxygen-16 has 8 neutrons, Oxygen-17 has 9 neutrons and Oxygen-18 will have 10 neutrons.

Answer 8

8 protons, 8 neutrons, 8 electrons.

Answer 9

Eight!

Answer 10

8
