Elementary Particles

Question Answer
Quarks6 types Up, Down, Top, Bottom, Charmed, Strange
Photons Quantum of light/other em. rad. Rest mass 0, spin 1
LeptonsOther particles, ex. neutrino, e-, muon and their antiparticles (Rest mass 1 or 0) (spin ½)
HadronsParticles built of 2-3 Quarks
BaryonsProtons and Neutrons (High rest mass) (spin ½)
MesonsPions, Kaons. (Rest mass bigger than muons, smaller than protons) (spin 0)
FermionsQuarks and Leptons (have non-integer spin)
BosonsPhotons, Gluones (have integer spin)
GluonsParticle to hold Quarks together in a Hadron
PionsMesons with 270x the mass of an electron
