Proton (disambiguation)

A proton is a subatomic particle with a positive fundamental electric charge of 1.6 × 10^-19 coulomb and a mass of 938 MeV — in other words, a hydrogen ion, specifically ¹H, which contains no neutrons.

Terms derived directly from this core meaning in particle physics include:
* Proton conductor, an electrolyte in which movable hydrogen ions are the primary charge carriers
* Proton decay, radioactive decay in which the proton decays into lighter subatomic particles in particle physics
* Proton emission, a type of radioactive decay in which a proton is ejected from a nucleus
* Proton-proton chain reaction, one of two fusion reactions by which stars convert hydrogen to helium
* Proton pump inhibitor, a group of drugs whose main action is pronounced and long-lasting reduction of gastric acid production
