Oxygen atom has an atomic number of 8 so it has 8 protons. O^2- will have two more electrons or 10. Neutrons: don't know. You didn't give a mass number. #protons + #neutrons = mass number. You know protons and when you know mass number you can calculate #neutrons.
protons: 8
neutrons: ?
electrons: 10
