Electron Rest Mass
The electron rest mass (me) is the mass of a stationary electron, equal to approximately 9.1094 × 10⁻³¹ kilograms or 0.51100 MeV/c². It is one of the fundamental physical constants and serves as the base unit of mass in atomic physics. The electron rest mass defines the scale of atomic and molecular energies and is used in quantum mechanics, particle physics, and relativistic calculations.
