WebThe electron mass (symbol: me) is the mass of a stationary electron, also known as the invariant mass of the electron. It is one of the fundamental constants of physics. It has a value of about 9.109 × 10−31 kilograms or about 5.486 × 10−4 daltons, which has an energy-equivalent of about 8.187 × 10−14 joules or about 0.511 MeV.

See more In physics, an electronvolt (symbol eV, also written electron-volt and electron volt) is the measure of an amount of kinetic energy gained by a single electron accelerating from rest through an electric potential difference of … See more An electronvolt is the amount of kinetic energy gained or lost by a single electron accelerating from rest through an electric potential difference of one volt in vacuum. Hence, it has a … See more In a low-energy nuclear scattering experiment, it is conventional to refer to the nuclear recoil energy in units of eVr, keVr, etc. This distinguishes the nuclear recoil energy from the "electron equivalent" recoil energy (eVee, keVee, etc.) measured by See more Mass By mass–energy equivalence, the electronvolt corresponds to a unit of mass. It is common in particle physics, where units of mass and … See more • Orders of magnitude (energy) See more • BIPM's definition of the electronvolt • physical constants reference; CODATA data See more helper feargames
