Energy atomic units
WebThe atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu. Other … Webencounter a competing atomic unit system in which some factors of 2 are absorbed into some of the units so the energy unit comes out half as large, 13.6 eV. That energy unit is called the rydberg, and you can distinguish the two systems by saying Hartree atomic units or Rydberg atomic units. In this class we will use only Hartree atomic units.)

Atomic units, like SI units, have a unit of mass, a unit of length, and so on. However, the use and notation is somewhat different from SI. Suppose a particle with a mass of m has 3.4 times the mass of electron.
