The 80 pages that link to Neutron, each with the reason it gives.
Atomic numberRelated: Neutrons change an atom’s mass number without changing its atomic number.
Chemical elementRelated: Neutron number varies among isotopes without changing elemental identity.
Beta decayRelated: Its conversion into a proton defines beta-minus decay.
Alpha particleRelated: Two neutrons complete the alpha particle’s four-nucleon nucleus.
Helium-4Related: Two neutrons complete helium-4’s nucleus and contribute to its binding.
Mass numberRelated: Each neutron contributes one unit to an atom’s mass number.
DeuteriumRelated: Deuterium differs from ordinary hydrogen by having one neutron.
Nuclear spinRelated: Its intrinsic spin is another constituent contribution to nuclear spin.
IsospinRelated: It is the other member of the nucleon pair related by isospin.
Fissile materialRelated: Neutrons trigger fission and propagate the chain reaction.
Mass defectRelated: Its mass completes the constituent-mass sum for a nucleus.
Up quarkRelated: Its single up quark combines with two down quarks to give zero net charge.
Down quarkRelated: Its two down quarks help give the neutron zero net electric charge.
Carbon isotopesRelated: Different neutron counts create carbon’s distinct isotopes.
Ida NoddackRelated: Noddack’s 1934 proposal specifically considered nuclei struck by neutrons.
Isotopes of nitrogenRelated: Changing the neutron count produces different nitrogen isotopes.
