lepton \lepton\ n. (Physics)
an elementary particle that participates in weak interactions
but does not participate in the strong interaction; it has a
baryon number of 0. Some known leptons are the electron,
the negative muon, the tau-minus particle, and the
neutrinos associated with each of these particles.

1. Amber; also, the alloy of gold and silver, called
electrum. [archaic]
[1913 Webster]
2. (Physics & Chem.) one of the fundamental subatomic
particles, having a negative charge and about one
thousandth the mass of a hydrogen atom. The electron
carries (or is) a natural unit of negative electricity,
equal to 3.4 x 10^-10 electrostatic units, and is
classed by physicists as a lepton. Its mass is
practically constant at the lesser speeds, but increases
due to relativistic effects as the velocity approaches
that of light. Electrons are all of one kind, so far as is
known. Thus far, no structure has been detected within an
electron, and it is probably one of the ultimate composite
constituents of all matter. An atom or group of atoms from
which an electron has been detached has a positive charge
and is called a cation. Electrons are projected from the
cathode of vacuum tubes (including television picture
tubes) as cathode rays and from radioactive substances
as the beta rays. Previously also referred to as
corpuscle, an obsolete term. The motion of electrons
through metallic conductors is observed as an electric
current. A particle identical to the electron in mass and
most other respects, but having a positive instead of a
negative charge, is called a positron, or antielectron

electron
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).
