Beta radioactivity also produces the neutrino and antineutrino, particles that have no charge and very little mass, symbolized by ν and of the parent nucleus.

The multipolarity of the gamma ray (magnetic dipole, M1, plus 0.005 percent electric quadrupole, E2) is indicated above the vertical arrow symbolizing the gamma transition.

Yet another type of radioactivity is spontaneous fission.

In this process the nucleus splits into two fragment nuclei of roughly half the mass of the parent.

The proton is the nucleus of ordinary hydrogen and is stable.
