The 88 pages that link to Proton, each with the reason it gives.

• Atomic numberRelated: Each proton in the nucleus contributes one unit to the atomic number.

• IsotopeBroader topic: An isotope retains the same proton count as other atoms of its element.

• ElectronCompared with: Unlike the electron, it is a massive composite particle made of quarks.

• Chemical elementBroader topic: Changing the number of these particles changes the element.

• Electric chargeRelated: Protons contribute positive charge to matter.

• NeutronCompared with: It shares nuclear membership with the neutron but determines an element's atomic number.

• Quantum chromodynamicsBroader topic: Its mass and internal structure emerge largely from QCD dynamics.

• Beta decayRelated: Its conversion into a neutron defines beta-plus decay.

• Nuclear binding energyBroader topic: Protons are among the constituents that must be separated to dismantle a nucleus.

• Big Bang nucleosynthesisRelated: Protons survived as hydrogen nuclei and combined with neutrons to form heavier light nuclei.

• Nuclear stabilityRelated: Proton number sets nuclear charge and the repulsion stability must overcome.

• Atomic nucleusBroader topic: Its number in a nucleus determines the element’s atomic number.

• Lewis acidBroader topic: A proton is a Lewis acid because it accepts a lone pair, but Lewis acids need not be protons.

• Brønsted–Lowry acid–base theoryBroader topic: The theory’s acid–base role is defined by donation or acceptance of this particle.

• Conjugate acid–base pairRelated: The one-proton difference is the defining feature of a conjugate pair.

• IonRelated: Protons provide the positive charge against which an ion's electrons are counted.

• Carbonic acidRelated: Acid behavior here centers on transfer of hydrogen ions, conventionally described as protons.

• GluonBroader topic: It is a familiar hadron whose internal binding depends on gluons.

• Hydrogen atomRelated: Its positive charge binds the hydrogen atom’s electron.

• Nuclear physicsBroader topic: Its charge helps determine nuclear composition and the electromagnetic repulsion nuclei must overcome.

• Alpha particleRelated: Two protons give an alpha particle its charge of +2.

• HadronBroader topic: The proton is a familiar hadron and the nucleus of ordinary hydrogen.

• Strong interactionBroader topic: Its internal quarks are bound by the fundamental interaction.

• Quark modelBroader topic: Its charge and quantum numbers follow from its valence-quark assignment.

• Atomic massBroader topic: Proton number identifies an element and contributes to its atomic mass.

• Elementary chargeRelated: A proton carries exactly one elementary charge.

• BaryonBroader topic: It is the lightest stable baryon and a constituent of atomic nuclei.

• AcidRelated: Brønsted acids donate hydrogen ions, which are protons in aqueous chemistry.

• PositronCompared with: Its positive charge can resemble a positron’s, but its mass and internal structure differ greatly.

• MuonCompared with: Unlike the elementary muon, the proton is a quark composite and remains stable under ordinary conditions.

• Nuclear forceRelated: Protons experience the nuclear force while also repelling one another electrically.

• Helium-4Related: Two protons give helium-4 its nuclear charge and elemental identity.

• Proton transferNarrower topic: In ordinary chemical transfer, the moving particle is a hydrogen nucleus rather than a neutral hydrogen atom.

• ProtonationBroader topic: Protonation names the addition of this particle, often transferred in solvated form.

• Conjugate acidRelated: Accepting this particle is what distinguishes a base from its conjugate acid.

• Conjugate baseRelated: The proton is the particle lost when a conjugate base forms.

• Mass numberRelated: Each proton contributes one unit to an atom’s mass number.

• Carbon-12Broader topic: Six protons give carbon-12 its atomic number and elemental identity.

• NucleonBroader topic: One of the two kinds of nucleons; its positive charge shapes nuclear structure.

• AtomBroader topic: An atom’s number of protons defines which chemical element it is.

• DeuteriumRelated: Its single proton gives deuterium the atomic number of hydrogen.

• Nuclear drip lineRelated: The proton drip line marks the limit to adding protons while retaining a bound nucleus.

• Nuclear spinRelated: Its intrinsic spin contributes to the total angular momentum of a nucleus.

• James ChadwickRelated: The radiation knocked protons from paraffin, whose recoil speeds revealed its particle-like collisions.

• AntiprotonCompared with: The proton has the same mass as the antiproton but opposite charge and baryon number.

• Charged particleBroader topic: It provides a familiar example of positive charge carried by a particle.

• Proton decayBroader topic: It is the particle whose hypothetical transformation defines proton decay.

• ATLAS experimentRelated: Protons are the colliding particles accelerated by the LHC for ATLAS data-taking.

• HydroniumRelated: Hydronium forms when water accepts a proton.
