1. That is one electron volt.

2. In Rutherford's experiment, the u-particles had energies of millions of electron volts.

3. If the LHC was operating at its full 7 trillion electron volt capacity, the colliding particles' energy would equal what you'd get from eating 0.00013 micrograms of a candy bar.

4. Therefore, when find a "new particle", should not only rely on "distinctive electron volt", first want to ask :"is it really one"?

5. What people did is they said let's define a unit of energy that represents a unit charge accelerated across a unit potential difference, and let's call that the electron volt.
