It would have 8 protons.

Explanation:

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.
