Hydrogen ion

Description

The terms hydrogen ion H⁺ and proton p are used synonymously in chemistry. A hydrogen ion is a negatively charged molecule. In particle physics, however, a proton is a submolecular and subatomic particle with a positive electric charge. The H⁺ ion has no electrons and is a bare charge with only about 1/64 000 of the radius of a hydrogen atom, and so is extremely reactive chemically with an extremely short lifetime in aqueous solutions, where it forms the hydronium ion H₃O⁺, which in turn is further solvated by water molecules in clusters such as H₅O₂⁺ and H₉O₄⁺. The transfer of H⁺ in an acid–base reaction is referred to as proton transfer. The acid is the H⁺ donor and the base is the H⁺ acceptor.

Abbreviation: H⁺
