In nuclear physics, the island of stability is a predicted set of isotopes of superheavy elements that may have considerably longer half-lives than known isotopes of these elements. It is predicted to appear as an "island" in the chart of nuclides , separated from known stable and long-lived primordial radionuclides .
In the periodic table of the elements, it is expected to be an s-block element, an alkaline earth metal, and the second element in the eighth period. It has attracted attention because of some predictions that it may be in the island of stability. Unbinilium has not yet been synthesized, despite multiple attempts from German and Russian teams.
Scientists have long searched for long-lived heavy isotopes outside of the valley of stability, [6] [7] [8] hypothesized by Glenn T. Seaborg in the late 1960s. [9] [10] These relatively stable nuclides are expected to have particular configurations of "magic" atomic and neutron numbers, and form a so-called island of stability.
In the periodic table of the elements, copernicium is a d-block transactinide element and a group 12 element. During reactions with gold , it has been shown [ 8 ] to be an extremely volatile element, so much so that it is possibly a gas or a volatile liquid at standard temperature and pressure .
Tennessine may be located in the "island of stability", a concept that explains why some superheavy elements are more stable despite an overall trend of decreasing stability for elements beyond bismuth on the periodic table. The synthesized tennessine atoms have lasted tens and hundreds of milliseconds.
Transuranic elements may be used to synthesize superheavy elements. [7] Elements of the island of stability have potentially important military applications, including the development of compact nuclear weapons. [8] The potential everyday applications are vast; americium is used in devices such as smoke detectors and spectrometers. [9] [10]
