Electron-volt (eV) and joule (J) are both units of energy commonly used in physics and chemistry, but they are often used in different contexts due to their relative sizes.
Electron-volt (eV)
An electron-volt is a unit of energy commonly used in the field of atomic and subatomic particle physics. It is defined as the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.
The electron-volt is a convenient unit for describing the energies of particles at the atomic and subatomic scale. 1 electron-volt is approximately equal to 1.602 x 10-19 joules.
Joule (J)
The joule is the standard unit of energy in the International System of Units (SI). It is defined as the amount of energy transferred or converted when a force of one newton acts over a distance of one meter. The joule is used to measure various forms of energy, including mechanical, thermal, and electromagnetic energy.
