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.

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.

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.

Electrons are found within atoms and surround the nucleus of protons and neutrons in a particular electron configuration. It is the electonic configuration of atoms that determines an element ’s physical and chemical properties.

The electron is a subatomic particle that is found in all atoms. Unlike protons, neutrons, or the nuclei of atoms, electrons are elementary particles. This means they are not made of even smaller particles. Also unlike protons and neutrons, electrons have essentially no mass.

Electronic configurations describe each electron as moving independently in an orbital, in an average field created by the nuclei and all the other electrons. Mathematically, configurations are described by Slater determinants or configuration state functions.
