Electron - Wikipedia
https://en.wikipedia.org/wiki/Electron
WEBThe electron ( e−. or. β−. ) 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] .
