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.

Wikipedia
The electron is a subatomic particle, symbol or , with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton. Quantum mechanical properties of the electron include an intrinsic angular momentum ( spin) of a half-integer value in units of ħ, which means that it is a fermion. Being fermions, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle. Like all matter, electrons have properties of both particles and waves, and so can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a higher De Broglie wavelength for typical energies.
Many physical phenomena involve electrons in an essential role, such as electricity, magnetism, and thermal conductivity, and they also participate in gravitational, electromagnetic and weak interactions. An electron generates an electric field surrounding it. An electron moving relative to an observer generates a magnetic field. External electromagnetic fields affect an electron according to the Lorentz force law. Electrons radiate or absorb energy in the form of photons when accelerated. Laboratory instruments are capable of containing and observing individual electrons as well as electron plasma using electromagnetic fields, whereas dedicated telescopes can detect electron plasma in outer space. Electrons are involved in many applications such as electronics, welding, cathode ray tubes, electron microscopes, radiation therapy, lasers, gaseous ionization detectors and particle accelerators.
Interactions involving electrons and other subatomic particles are of interest in fields such as chemistry and nuclear physics. The Coulomb force interaction between positive protons inside atomic nuclei and negative electrons composes atoms. Ionization or changes in the proportions of particles changes the binding energy of the system. The exchange or sharing of the electrons between two or more atoms is the main cause of chemical bonding. British natural philosopher Richard Laming first hypothesized the concept of an indivisible quantity of electric charge to explain the chemical properties of atoms in 1838; Irish physicist George Johnstone Stoney named this charge 'electron' in 1891, and J. J. Thomson and his team of British physicists identified it as a particle in 1897. Electrons can also participate in nuclear reactions, such as nucleosynthesis in stars, where they are known as beta particles. Electrons may be created through beta decay of radioactive isotopes and in high-energy collisions, for instance when cosmic rays enter the atmosphere. The antiparticle of the electron is called the positron; it is identical to the electron except that it carries electrical and other charges of the opposite sign. When an electron collides with a positron, both particles may be totally annihilated, producing gamma ray photons.
An electron is a subatomic particle.

Electron is a fictional character appearing in American comic books published by Marvel Comics.
Electron is a warrior serving in the Royal Elite of the Shi'ar Imperial Guard. He is a Shi'ar with the ability to generate and control electromagnetism. He was born on Chandilar, the throne world of the Shi'ar Empire.
Electron was the computer handle of Richard Jones, a member of an underground hacker community called The Realm. Jones, born in June 1969, was one of three members of the group arrested in simultaneous raids by the Australian Federal Police in Melbourne, Australia, on 2 April 1990. All three — Nahshon Even-Chaim (also known as Phoenix), Electron and Nom (real name David John Woodcock) — were convicted of a range of computer crimes involving the intrusion into US defense and government computer systems and the theft of an online computer security newsletter in the late 1980s and early 1990.
Electron is a genus of the motmots, a family of Neotropical near passerine birds. The genus has two species:
- Keel-billed motmot, Electron carinatum
- Broad-billed motmot, Electron platyrhynchum
Both inhabit humid evergreen tropical forest. Both occur in Central America, and the broad-billed motmot occurs in a large region of South America as well.
They are distinguished from other motmots by their much wider bills. The rackets on their tails are less dramatic than those of many other motmot species and may be absent. The species are very similar except in adult plumage (but the adult keel-billed resembles the juvenile broad-billed). A mixed pair apparently courting has been observed (Howell and Webb 1995).
The name Electron is a Latinization of the Ancient Greek word for amber, and can mean "bright" in scientific names (Jaeger 1978). The name was given 46 years before an elementary particle was named electron.
Electron (formerly known as Atom Shell) is an open-source framework developed by GitHub. It allows for the development of desktop GUI applications using the Node.js runtime, originally used for the development of backend web applications. Electron is the main framework behind two notable open-source Source code editors: GitHub's Atom, and Microsoft's Visual Studio Code.
A basic Electron app consists of three files: package.json (metadata), main.js (code) and index.html ( graphical user interface). The framework is provided by the Electron executable file (electron.exe in Windows, electron.app on OS X and electron on Linux). Developers wishing to add branding and custom icon can rename and/or edit the Electron executable file.

Usage examples of "electron".
Particle accelerators are based on the same principle: They hurl bits of matter such as electrons and protons at each other as well as at other targets, and elaborate detectors analyze the resulting spray of debris to determine the architecture of the objects involved.
