Particle Physics
the lightest elementary particle with an electric charge: it is a lepton with a negative charge of c. 1.602 × 10-19 coulomb and a rest mass of c. 9.109 × 10-31 kg (c. 0.511 MeV/c2), which is c. 1⁄1836 of the mass of a proton: ordinarily an atom has the same number of negative electrons around the nucleus as the number
of positive protons in the nucleus

Electron
see synonyms of electronn. Abbr. e
A stable elementary particle in the lepton class having a negative electric charge of 1 elementary unit (about 1.602 × 10-19 coulombs) and a mass of about 9.11 × 10-28 grams. Electrons are found in shells orbiting the nuclei of atoms and can also move freely through space as cathode rays in a cathode-ray tube or as beta particles emitted by radioactive nuclei, or flow in a current through a conducting material impelled by an electric potential difference.
