I assume you mean the neutral oxygen. The one on the periodic table. It's mass number (atomic mass rounded up/down) is 16. The atomic number is the amount of protons and neutrons in a single atom. Then you subtract the atomic number from the mass number and you get the neutrons.

Answer:
8 protons, 8 electrons, and 8 neutrons. Simple, no?

In oxygen-16, the most common stable isotope, there are 8 protons and 8 neutrons in the nucleus, and 8 electrons in a neutral atom circling outside.
