, is a key object of Arrhenius' definition of acid. Other hydrated forms, the Zundel cation H 5O+ 2 which is formed from a proton and two water molecules, and the Eigen cation H 9O+ 4, a hydronium ion and three water molecules, play an important role in hydron hopping according to the Grotthuss mechanism.nlike other ions, the hydron consists only of a bare atomic nucleus. The hydron (a completely free or naked hydrogen atomic nucleus) is too reactive to occur in many liquids, even though it is sometimes visualized to do so by students of chemistry.
