- n. A stable subatomic particle in the lepton family having a rest mass of 9.1066 × 10-28 grams and a unit negative electric charge of approximately 1.602 × 10-19 coulombs. See Table at subatomic particle.

- n. Same as electrum.
- n. In phys. chew., the definite charge of electricity which is associated with a univalent ion. Sometimes called an atom of electricity. See electricity.
- n. According to a recent hypothesis, a minute particle detached from an atom of a gas by certain agencies, as when the gas is carrying an electric current. The electron has a mass of something like one thousandth of the mass of an atom of hydrogen, and possesses (or consists of) a negative electric charge equal to that of the negative univalent ion of electrolytic conduction. In a gas at very low pressures, the electron constitutes the negative ion of gaseous conduction, while the atom from which the electron has been detached constitutes the positive ion. In gases at greater pressures, electrically neutral molecules become attached to the electron and to the atom from which the electron has been detached, and these complex systems constitute the ions of gaseous conduction at atmospheric pressure. In liquid electrolytes, according to this theory, an atom or radical from which one, two, or three electrons have been detached is a positive univalent, bivalent, or trivalent ion. An atom or radical to which one or more electrons have been attached constitutes a negative ion of the corresponding valence. In metallic conductors the electrons pass from an atom to an adjacent atom without producing electrolysis or chemical decomposition. The experimental basis of the hypothesis has been chiefly discovered by J. J. Thomson, with the aid of some of his pupils.
- n. physics The subatomic particle having a negative charge and orbiting the nucleus; the flow of electrons in a conductor constitutes electricity.
- n. chemistry, obsolete Alloys of magnesium and other metals, like aluminum or zinc, that were manufactured by the German company Chemische Fabrik Griesheim-Elektron.

- n. (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 raysand 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
- n. an elementary particle with negative charge

“The proton and the neutron have a diameter of 10-15m (a femtometre or a millionth of a millionth of a millimetre) and the electron is at least 1,000 times smaller.”
“Its resolving power could be considered theoretically unlimited, since the electron is a pointlike particle, However, according to quantum mechanics, every particle has wave characteristics which introduce an uncertainty into the determination of its position.”
“It had been known since long that the electron is a small magnet.”

“Shortly after the virus isolation, my co-workers and I were able to show that it was not immunologically related to HTLV, and in electron microscopy, it was very different from HTLV viral particles.”
“A theoretical model for the appearance of an electron is just that.”
“Sometimes an electron from a high-energy level drops to a lower energy level.”
“The spin of an electron is a well-known example (it can only have projections +1/2 or − 1/2 on any direction in space).”
“An electron is as point-like an object as can be: it has no internal structure as far as we know, except possibly on the Planck scale (for which you need string theory and that's again quantum mechanics).”
“As for that electron-spin skirmish we had a few months ago, he tried very hard with red-herrings and conflation of "electron movement" to try and label electron spin as just a hyphotheses.”
