Antiparticles have the same mass, the same average life and the same spinSpin is a characteristic property of elementary particles. as the corresponding particles, but opposite and equal baryonElementary particles with a baryon number = 1, this means: n... and lepton"Light" elementary particle. Leptons include elementary part... numbers. Antiparticles and particles are either both electrically neutral or they have an equal electric charge, but opposite signs.
