antiparticle particle    uncertainty principle Particles with identical mass and spin as those of ordinary matter, but with opposite charge. Antimatter has been produced experimentally, but little of it is found in nature. Why this should be so is one of the questions that must be answered by any adequate theory of the early universe.    
baryon fermionFermi-Dirac statistics3 1/2 or 3/2exclusion principle Heavy subatomic particle composed of 3 quarks.    
charged particle particle    uncertainty principle A particle with non-zero chargenon-zero  electric or magnetic fields
radioactive particlethe total energy produced when the particle decaysparticle    uncertainty principlethe products produced immediately after decayA particle which can produce harmful radioactivity directly through its decay or by interacting with other particles. The average time in which a particle decays
