Hydron

In chemistry, the hydron, informally called the proton, is the cationic form of atomic hydrogen, represented with the symbol H. The general term "hydron", endorsed by IUPAC, encompasses cations of hydrogen regardless of isotope: thus it refers collectively to protons (H) for the protium isotope, deuterons (H or D) for the deuterium isotope, and tritons (H or T) for the tritium isotope.
