Hartree Energy
The Hartree energy (Eh) is a unit of energy used in atomic physics, representing the total energy of an electron in a hydrogen atom in its ground state.
History/Origin
Named after the American physicist Douglas Hartree, the Hartree energy was introduced in the early 20th century as a fundamental atomic unit of energy within the system of atomic units, facilitating calculations in quantum mechanics.
Current Use
The Hartree energy is primarily used in theoretical and computational chemistry and physics to express energies at the atomic and molecular scale, especially in quantum chemistry calculations and atomic physics research.
Electron-Volt
An electron-volt (eV) is a unit of energy equal to the amount of kinetic energy gained or lost by an electron when it is accelerated through an electric potential difference of one volt.
History/Origin
The electron-volt was introduced in the early 20th century as a convenient unit for expressing atomic and subatomic energies, especially in quantum physics and particle physics, replacing larger units like the joule for small-scale energies.
Current Use
The electron-volt is widely used in physics and chemistry to quantify energies at the atomic and subatomic levels, such as in spectroscopy, particle physics, and quantum mechanics, due to its convenience in expressing small energy values.
