Electron : \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.

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).
