Webster's 1913 Dictionary
  1. \E*lec"tron\, n. [NL., fr. Gr. 'h`lektron. See
    Amber; also, the alloy of gold and silver, called {electrum}.
  2. \E*lec"tron\, [NL., fr. Gr. ?. See {Electric}.]
    (Physics & Chem.)
    One of those particles, having about one thousandth the mass
    of a hydrogen atom, which are projected from the cathode of a
    vacuum tube as the cathode rays and from radioactive
    substances as the beta rays; -- called also corpuscle. The
    electron carries (or is) a natural unit of negative
    electricity, equal to 3.4 x 10^{-10} electrostatic units. It
    has been detected only when in rapid motion; its mass, which
    is electromagnetic, is practically constant at the lesser
    speeds, but increases as the velocity approaches that of
    light. Electrons are all of one kind, so far as known, and
    probably are the ultimate constituents of all atoms. An atom
    from which an electron has been detached has a positive
    charge and is called a coelectron.
Computing Dictionary

A sub-atomic particle with a negative quantised charge. A flow of electrical current consists of the unidirectional (on average) movement of many electrons. The more mobile electrons are in a given material, the greater it electrical conductance (or equivalently, the lower its resistance).

Biology Dictionary
 Definition: A stable atomic particle that has a negative charge; the flow of electrons through a substance constitutes electricity.
