It would have #8# protons.


Elements are distinguished by the number of protons in their nucleus. This number is called the atomic number, and for Oxygen, it is #8#.

Thus, any atom of Oxygen, whether positive or negative, will have #8# protons. If it is positively charged, this simply means that it has # <8# electrons such that the net charge is positive.
