    en.wikipedia.org/wiki/Proton

    A proton is a stable subatomic particle, symbol. p. , H +, or 1 H + with a positive electric charge of +1 e ( elementary charge ). Its mass is slightly less than the mass of a neutron and 1,836 times the mass of an electron (the proton-to-electron mass ratio ). Protons and neutrons, each with masses of approximately one atomic mass unit, are ...
