atomic nucleus
nukleo atomikoa

the atomic radius is the distance from the atomic nucleus to the outmost stable electron orbital in a atom that is at equilibrium.
erradio atomikoa atomo egonkor batean kanpoen dagoen elektroi orbita egonkorretik nukleora dagoen distanzia da.

matter that cannot be broken down into simpler matter. chemical elements are cornerstones of materials. elements consist of atoms that consist of a nucleus of positive protons, neutral neutrons, and a shell of electrons.
materia sinpleagotan banatu ezin daitekeen materia. elementu kimikoak materialeen kantoiharriak dira. elementuak protoi positibo eta neutroi neutrodun nukleo batez eta elektroi oskol batez osatutako atomoz osatuta dago.

a nuclear isomer is a metastable or isomeric state of an atom caused by the excitation of a proton or neutron in its nucleus so that it requires a change in spin before it can release its extra energy. they decay to lower energy states of the nuclide through two isomeric transitions: [br] - > & #947; - emission (emission of a high-energy photon)[br] - > internal conversion (the energy is used to ionize the atom)[br] contrast this with the definition of a chemical isomer, the more common use of the word. also contrast with the meaning of isotope, in which the difference is the number of neutrons in the nucleus. metastable isomers of a particular atom are usually designated with an "m" (or, in the case of atoms with more than one isomer, 2m, 3m, and so on). this designation is usually placed after the atomic symbol and number of the atom (e. g., co-58m), but is sometimes placed as a superscript before (e. g., [sup]m[/ sup]co-58 or [sup]58m[/ sup]co).
isomero nuklear bat, energia gehiarria askatzeko bere spina aldatu behar duen nukleoko protoi edo neutroi kitzikadura batek sortutako atomo baten metaegonkor edo egoera isomeriko bat da. bi transizio isomerikoren bidez nuklido aren energia baxuagoko egoerara desintegratzen dira. [br] - > & # 947; - igorpena (energia handiko fotoien igorpena) [br] - > berna bihuketa (atomoa ionizatzeko erabiltzen den energia) [br] hau isomero kimiko baten definizioaren parean jarri, hitzaren erabilpen normalena. isotopoaren esanahiarekin parekatu, diferentzia nukleoko neutroi kopurua da. atomo jakin baten isomero metaegonkorrak normalean "m" letrarekin izendatzen dira (edo isomero bat baina gehiago dituztenetan 2m, 3m...). izendapena normalean sinbolo atomikoaren eta atomoaren zenbakiaren ondoren jartzen da (adib. co- 58m), baina batzutan aurreko goi- indize bezala ere jartzen da (adib. [sup] m [/ sup] co- 58 or [sup] 58m [/ sup] co).
