Oxygen-16 atomic number is 8 so it has 8 protons. Its atomic weight is 16 so 16-8 = 8 neutrons.
Hope I helped. :)
Answer: The given element has 8 protons and 8 neutrons in it. ;
An oxygen atom represented as 8 16 O contains 8 protons and 8 neutrons. The atomic number, which is 8, indicates the number of protons, and the atomic mass number, 16, tells us that there are 8 neutrons when calculated with the formula. Therefore, oxygen has an equal number of protons and neutrons in this isotope.
