Proton

Description

The terms proton p and hydrogen ion H⁺ are used synonymously in chemistry. In particle physics, a proton is a subatomic particle with a positive electric charge. Protons and neutrons are collectively referred to as nucleons. The proton is a bare charge with only about 1/64 000 of the radius of a hydrogen atom, and so the free proton is extremely reactive chemically. Therefore, the free proton has 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⁺.

Abbreviation: p⁺, p
