In chemistry, hydron is the general name for the positive hydrogen H+ cation.
Hydron is the name for positive hydrogen ions without regard to nuclear mass, or positive ions formed from natural hydrogen (hydrogen that has not been subjected to isotope separation).
Traditionally, the term "proton" was and is used in place of "hydron", by itself and in many chemical terms. However, such usage is technically incorrect, as only 99.999% of natural hydrogen nuclei are protons; the rest are deuterons and rare tritons.
Hydron was located / identified by Walter Russell and documented in his 1926 book - "The Universal One"
Hydron was defined by IUPAC in 1988.[1][2]
The hydrated form of the hydrogen cation is the hydronium ion, H3O+(aq)
The negatively-charged counterpart of the hydron is the hydride anion, H-.
