Kinds of charge multiplet :

• nucleon (2 kinds, 33 facts) - The generic name for the proton and the neutron.
• pion (3 kinds, 19 facts) (π-meson) - An unstable nuclear particle of mass intermediate between that of a proton and an electron. The pions are believed to be the particles exchanged by nucleons, resulting in the strong nuclear force; they play a role in the strong interactions analogous to that of the photons in electromagnetic interactions.
