Grand unified theories have typically predicted the decay of these into a pion and a positron, but experiments estimate that their theoretical minimum half-life is on the order of 10 to the 36 years. They were discovered when Ernest  Rutherford's scintillation detectors saw their signature after he shot alpha particles into nitrogen atoms, and they can be created by beta decay. They are composed of two up and one down quark, have spin of one half, and after electron  capture they transform into another baryon. FTP, name this positively-charged nucleon that determines elements‘ atomic  number.
