The electron (e −, or β − in nuclear reactions) is a subatomic particle with a negative one elementary electric charge. [13] Electrons belong to the first generation of the lepton particle family, [14] and are generally thought to be elementary particles because they have no known components or substructure. [1]

Electron (formerly known as Atom Shell[5]) is a free and open-source software framework developed and maintained by OpenJS Foundation. [6] .

An electron is a very small piece of matter. Its symbol is e −, and it was discovered by J. J. Thomson in 1897. The electron is a subatomic particle. Every atom is made of some electrons that surround the nucleus of the atom. An electron can also be separate from any atom.

The elementary charge, usually denoted by e, is a fundamental physical constant, defined as the electric charge carried by a single proton (+1 e) or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e.

2018年12月8日 · Here is the definition of the electron, along with its word origin, history, and interesting facts. An electron is a stable subatomic particle with a negative electrical charge. Unlike protons and neutrons, electrons are not constructed from even smaller components.

2025年1月8日 · Electron, lightest stable subatomic particle known. It carries a negative charge of 1.6 x 10^-19 coulomb, which is considered the basic unit of electric charge. The electron was discovered in 1897 by the English physicist J.J. Thomson during investigations of cathode rays.

2025年1月9日 · electron (plural electrons) The subatomic particle having a negative charge and orbiting the nucleus; the flow of electrons in a conductor constitutes electricity. Synonyms: e (symbol); negatron (obsolete) Hypernyms: subatomic particle < particle Holonym: atom Comeronyms: proton, p, neutron, n; nucleon, baryon

2024年8月28日 · The electron was discovered in 1879 by J. J. Thompson when he was investigating the bright glow observed on a phosphorescent screen when a high voltage is applied across two electrodes in a partially evacuated tube – a cathode ray tube.

2023年12月17日 · Electron is a subatomic particle having a negative electric charge. It is one of the three fundamental subatomic particles, along with protons and neutrons, that form atoms. Electrons can be found primarily in two states, which are:
