The electron (e−, or β− in nuclear reactions) is a subatomic particle with a negative one elementary electric charge. Matter that contains a different number of electrons and protons is electrically charged, giving electrons their name. Because electrons are much less massive than protons, electrical charge is the primary way we observe their effects at human scale. Characterization.
