Weegy: There are two kinds of particles:
hadrons which feel the strong nuclear force, the force that holds protons and neutrons together in the atomic nucleus; and
leptons, which do not feel that force, [ the electron being the best-known example.
There are only a few leptons:
the heavier "electron-like" particle the muon, and
the electrically neutral, massless or very-low-mass neutrino.
