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]

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.

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

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.

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.

2024年5月21日 · An electron is a subatomic particle with a negative electric charge that is equal, but opposite to, the positive charge of a proton. These two particles, together with neutrons, form atoms, with the protons and neutrons residing in the nucleus, and the electrons in surrounding orbitals, held in place by the electromagnetic force. They are ...

2025年3月28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.

In chemistry and atomic physics, an electron shell may be thought of as an orbit that electrons follow around an atom's nucleus. The closest shell to the nucleus is called the "1 shell" (also called the "K shell"), followed by the "2 shell" (or "L shell"), then the "3 shell" (or "M shell"), and so on further and further from the nucleus.
