IT'S POSITIVE. WHEN THE FIRST EXTRA ELECTRON IS ADDED TO AN ISOLATED OXYGEN ATOM IN GROUND STATE, THE ELECTRON-ELECTRON REPULSIONS WITHIN THE O ATOM BECOME SO HIGH( AS THE O ATOM IS SMALL), THAT ADDING AN ONE MORE ELECTRON REQUIRES A LARGE AMOUNT OF ENERGY. THIS MAKES ITS SECOND E GAIN ENTHALPY POSISTIVE.
