  "term": "Electron rest mass",
  "field": "Chemistry",
  "definition": "The invariant mass of an electron when it is at rest, a fundamental physical constant. It represents the intrinsic mass of the electron, independent of its motion or interactions. This value is approximately 9.109 x 10^-31 kilograms and is a key parameter in quantum electrodynamics and atomic physics calculations.",
