nuclide
a nuclide is a species of an atom with a specific number of protons and neutrons in the nucleus, for example carbon-13 with 6 protons and 7 neutrons. the "nuclide" concept (referring to individual nuclear species) emphasizes nuclear properties over chemical properties, whereas the "isotope" concept (grouping all atoms of each element) emphasizes chemical over nuclear. the neutron number has large effects on nuclear properties, but its effect on chemical properties is negligible for most elements. even in the case of the lightest elements where the ratio of neutron number to atomic number varies the most between isotopes it usually has only a small effect, although it does matter in some circumstances (for hydrogen, the lightest element, the isotope effect is large enough to strongly affect biology). the term "isotopes" (originally also "isotopic elements", now sometimes "isotopic nuclides") is intended to imply comparison (like "synonyms" or "isomers"), for example: the nuclides , , are isotopes (nuclides with the same atomic number but different mass numbers), but , , are isobars (nuclides with the same mass number). however, because "isotope" is the older term, it is better known than "nuclide", and is still sometimes used in contexts where "nuclide" might be more appropriate, such as nuclear technology and nuclear medicine.

section::::different nuclear clock concepts.:the single-ion nuclear clock.





























two differenct concepts for a nuclear optical clock have been discussed in literature. the first concept, known as the single-ion nuclear clock, uses the nucleus of an individual trapped and laser-cooled ion for laser stabilization. such a clock is expected to achieve the highest time accuracy, as the ion is to a large extent isolated from its environment. there is no conceptual hindrance to also use an ion cloud for the purpose of laser stabilization.
