e·lec·tron
(ĭ-lĕk′trŏn′)n. 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.
[electr(ic) + (i)on.]

e•lec•tron
(ɪˈlɛk trɒn)n.
1. an elementary particle that is a fundamental constituent of matter, having a negative charge of 1.602 x 10−19 coulombs, and existing independently or as the component outside the nucleus of an atom.
2. a unit of charge equal to the charge on one electron.

e·lec·tron
(ĭ-lĕk′trŏn′) A stable subatomic particle with a negative electric charge. Electrons spin about an atom's nucleus in orbits called shells. Electrons behave both as particles and as waves, and their motion generates electric and magnetic fields. Though the electron is the lightest subatomic particle, its charge is as great as that of a proton. See more at atom.

electron
1. One of the three basic subatomic particles. It is very light and orbits round the nucleus of an atom. It has a negative charge.
2. A subatomic particle carrying a negative charge.
