8p, 8e, 8n

when you look at the periodic table, its atomic number is 8. thats how many protons it has. an atom always has the same amount of protons as electrons, so it has 8 electrons. Finally, to figure out the amount of neutrons you subtract the rounded estimated weight (15.99-->16) minus the atomic number, so 16-8, which is 8 neutrons.
