I had the pleasure of hearing Abdus Salam give a talk in Oxford, sometime around 1960. I naïvely asked why a neutron would decay into a proton and electron, rather than an antiproton and positron, and he gently explained to me the concept of baryon number, which I would have known about by that point if I had been paying proper attention to his talk. Both prose and neutron have baryon (heavy particle) number +1, while their antiparticles have baryon number -1. They also have lepton (like particle) number 0, which is why the neutron decays into a proton, and electron, and an antineutrino.
