How many neutrons in o16?

There are 8 neutrons in an oxygen-16 atom. Oxygen has an atomic number of 8 and with an atomic mass of 16, it is simple to calculate the number of neutrons by subtracting the atomic number (8) from the atomic mass (16). The 16 - 8 = 8.


How many protons electron and neutrons are in the element oxygen?

There are always 8 protons in Oxygen. This is represented by the atomic number of oxygen. As for electrons , they are often represented by the atomic number in the neutral form, 8, but if the oxygen atom is a ion it would have 10 electrons. For neutrons the average atomic mass is 16.01, neutrons are found by subtracting the number of protons from the atomic mass, so 16.01-8=8.01, there 8.01 average neutrons in oxygen, but in isotopes oxygen can have differnet amounts of neutrons, the mainest is 8 neutrons.
