Antiparticles 2
Antiparticles 2 : Antiparticles have the same mass, the same average life and the same spin as the corresponding particles, but opposite and equal baryon and lepton numbers. Antiparticles and particles are either both electrically neutral or they have an equal electric charge, but opposite signs.
