An electron volt, eV, is a unit of energy. Which is larger, a GeV or a MeV?
Solution 58E 19 Electron volt is a unit of energy equal to approximately 1.6 × 10 joules.it is also the amount of energy gained or lost by charge of an single electron moving across an electric potential difference of one volt.here larger is GeV and smaller is MeV . 6 MeV = 10 eV = 1 million electron volts. GeV = 10 eV = 1 billion electron volts.
