Electron-volt
eV
Definition
An electron-volt (symbol: eV) is a unit of energy used in atomic and particle physics, equal to approximately 1.602 × 10^-19 joules. It represents the kinetic energy gained by an electron when accelerated through a potential difference of one volt.
History/Origin
The electron-volt was introduced in the early 20th century for describing atomic and particle energies. It became essential in atomic physics, quantum mechanics, and particle physics research, providing a convenient energy scale for subatomic particles.
Current Use
Electron-volts are used in atomic physics for describing atomic energy levels, in particle physics for measuring particle energies, in semiconductor physics for band gap energies, and in nuclear physics for nuclear reaction energies.
