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

-|description='''Proton''' and '''hydrogen ion''', H+, are terms used synonymously in chemistry. A proton or hydrogen ion has no electrons and corresponds to a bare nucleus. The proton is a bare charge with only about 1/64,000 of the radius of a hydrogen atom, and so is extremely reactive chemically. 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 H<sub>5</sub>O<sub>2</sub><sup>+</sup> and H<sub>9</sub>O<sub>4</sub><sup>+</sup>.
