Energy required to move an electron through a potential difference of 1 volt. An electron volt is equivalent to 1.6×10-19 J.
A unit of energy that is convenient to use on the atomic scale, equal to the amount of work required to move an electron, with its negative charge, through an electrical potential of one volt, 1.6 x 10-19 joules. Chemical reactions at the atomic scale involve energies of a few eV, for example, combining two molecules of hydrogen (H2) with a single molecule of oxygen (O2) to make two molecules of water (H2O) releases 5 eV. Nuclear reactions release much more energy. Fission of a uranium-235 nucleus by a neutron releases 200 MeV -- 200 million electron volts. The fusion of deuterium with tritium releases 17.9 MeV, which, because the mass of the deuterium and tritium are so small, is 500 times the energy released by fission, per kilogram of fuel, and 100-million times the energy released by burning coal.

3/4 A unit of energy equal to the kinetic energy acquired by an electron when accelerated through a potential difference of 1 volt (1 eV = 1.6 × 10-19J).
the energy imparted to an electron passing through a potential difference of one volt.
A measure of the energy gained by an electron falling through an electric field produced by one volt.
The energy imparted to an electron when it is moved through a potential difference of 1 volt. It is equivalent to 1.6 x 10-12 ergs. See; Electron.
An electron Volt (eV) is a unit of energy. Technically, it is the energy an electron or proton gains when it moves through a potential difference of 1 Volt. Potential difference is the work per unit charge done externally to move a charge from point A to point B without causing a change in potential energy. This unit is commonly used when referring to the energy of X-rays. Often, the prefix "kilo" is put in front of it. Kilo means 1000, so a kilo-electron Volt or keV is equal to 1000 eV. A Mega-electron Volt, or MeV, is equal to one million eV. A GeV is a Giga-electron Volt - or a billion eV.
A unit of energy, sufficient to excite atoms to emit visible light. (1 keV=1000 eV, 1 MeV=1000 keV, 1 GeV=1000 MeV)

A keV (or kilo-electron volt) is equal to one thousand electron volts. An MeV (mega-electron volt) is equal to one million electron volts. A GeV (giga-electron volt) is equal to one billion (109) electron volts. More about electron volts...
Abbreviated eV. A unit of energy used to describe the total energy carried by a particle or photon. The energy acquired by an electron when it accelerates through a potential difference of 1 volt in a vacuum. 1 eV = 1.6 × 10-12 erg.

A hydrogen atom can be ionized by absorbing a photon of energy 13.6 eV, or wavelength 912 Angstroms. X-rays are generally taken to have energies from about 0.5-10 thousand eV (kilo-eV or keV), while gamma rays have energies in the million-eV (MeV), billion-eV (giga- or GeV) range or even higher.
(ev)--a convenient unit of energy applied to ions and electrons, equal to the energy gains when such particles "fall" across a voltage difference of 1 volt. Gas molecules at room temperature have about 0.03 ev, on the Sun about 0.6 ev, typical electrons of the aurora 5000 ev, typical protons in the inner radiation belt 20,000,000 ev, typical cosmic ray protons near Earth 10,000,000,000 ev, and the highest energies of cosmic rays may reach up to 1,000,000,000 times more.

A unit of energy that is equal to the energy that an electron gains as it moves through a potential difference of one volt. This very small amount of energy is equal to 1.602 * 10-19 joules. Because an electron volt is so small, engineers and scientists sometimes use the terms MeV (mega-million) and GeV (giga-billion) electron volts.
A unit used to measure the energy of subatomic particles in a particle accelerator.
