=== Atomic nuclei ===

[[Atomic nucleus|Atomic nuclei]] typically consist of protons and neutrons, although exotic nuclei may consist of other baryons, such as [[hypertriton]] which contains a [[hyperon]]. These baryons (protons, neutrons, hyperons, etc.) which comprise the nucleus are called nucleons. Each type of nucleus is called a "[[nuclide]]", and each nuclide is defined by the specific number of each type of nucleon.
* "[[Isotope]]s" are nuclides which have the same number of protons but differing numbers of neutrons.
* Conversely, "[[isotone]]s" are nuclides which have the same number of neutrons but differing numbers of protons.
* "[[Isobar (nuclide)|Isobar]]s" are nuclides which have the same total number of nucleons but which differ in the number of each type of nucleon. [[Nuclear reaction]]s can change one nuclide into another.
