4 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: 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. From Webster's Revised Unabridged Dictionary (1913) [web1913]: Electron \E*lec"tron\, n. [NL., fr Gr 'h`lektron. See {Electric}.] Amber; also the alloy of gold and silver, called {electrum}. From WordNet r 1.6 [wn]: electron n : an elementary particle with negative charge From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: electronA 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). (1995-10-06)
