Attojoule

The attojoule (aJ) is a unit of energy in the International System of Units (SI). It is equal to one quintillionth of a joule (0.000000000000000001 J). The attojoule is commonly used to measure extremely small amounts of energy, such as the energy content of individual photons.

Origin:

The attojoule is derived from the joule, which is named after James Prescott Joule, an English physicist. The prefix 'atto-' signifies a factor of one quintillionth, making the attojoule equal to one quintillionth of a joule.

Hartree energy

The Hartree energy (Eₕ) is a unit of energy used in atomic physics and quantum chemistry. It is equal to the energy of an electron in the ground state of a hydrogen atom.

Origin:

The Hartree energy is named after the British physicist Douglas Hartree, who developed the Hartree-Fock method for calculating the wave functions of electrons in atoms and molecules.
