How many protons are in an oxygen atom?
Explanation
The answer is not eight, it is actually 8. An oxygen atom has 8 protons in its nucleus. Protons are subatomic particles with a positive charge, and the number of protons in an atom determines its atomic number, which is unique for each element. Since oxygen has an atomic number of 8, it means that there are 8 protons present in the nucleus of an oxygen atom.
