Linked from

The 106 pages that link to Electron, each with the reason it gives.

• PhotonCompared with: Electrons carry electric charge and rest mass; photons carry neither.

• ProtonCompared with: Its opposite charge balances the proton in electrically neutral atoms.

• NeutronCompared with: Unlike the neutron, it is elementary, negatively charged, and not a nuclear constituent.

• Atomic nucleusCompared with: Electrons shape atomic size and chemistry, while the nucleus holds most atomic mass.

• John DaltonCompared with: The electron’s discovery overturned Dalton’s claim that atoms are indivisible.

• PositronCompared with: It has the positron’s mass and spin but the opposite electric charge.

• MuonCompared with: The electron shares the muon’s charge and interactions but is far lighter and stable.

• NucleonCompared with: Unlike nucleons, electrons are leptons and are not constituents of the nucleus.

• James ChadwickCompared with: Unlike electrons, neutrons are massive, neutral constituents of atomic nuclei.

• QuasiparticleCompared with: In a solid, an electron can acquire effective properties and become an electron quasiparticle.

• Up quarkCompared with: Unlike the up quark, it is a lepton and does not carry color charge.

• Discovery of the neutronCompared with: Its small mass could not account for the energetic proton recoils as well as a neutron could.

• Dirac seaCompared with: The sea treats ordinary electrons as excitations above the filled negative-energy background.
