| a type of neutrino that obeys a conservation law together with the electron, with the total number of electrons and electron-neutrinos minus the total number of their antiparticles remaining constant. |
| electron neutrino n. A stable elementary particle in the lepton family having a mass of zero, or very close to zero, and no charge. See Table at subatomic particle. |
| electron neutrino
A type of neutrino associated with the electron, often created in particle interactions involving electrons (such as beta decay). The electron neutrino has a mass of zero or nearly zero, and has no electric charge. See more at neutrino. See Table at subatomic particle. |
