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 .

Einsteinium and fermium were discovered by a team of scientists led by Albert Ghiorso in 1952 while studying the composition of radioactive debris from the detonation of the first hydrogen bomb. [19] The isotopes synthesized were einsteinium-253, with a half-life of 20.5 days, and fermium-255 , with a half-life of about 20 hours.
Subsequent work at the JINR laboratory at Dubna, led by Yuri Oganessian and a Russian-American team of scientists, was successful in identifying elements 113–118 (113, nihonium; 114, flerovium; 115, moscovium; 116, livermorium; 117, tennessine and 118, oganesson), thereby completing the Period 7 elements of the periodic table of the elements.
It is expected that moscovium will have an inert-pair effect for both the 7s and the 7p 1/2 electrons, as the binding energy of the lone 7p 3/2 electron is noticeably lower than that of the 7p 1/2 electrons. This is predicted to cause +I to be a common oxidation state for moscovium, although it also occurs to a lesser extent for bismuth and ...
The data was consistent with that found in the first experiments in 2003. This reaction was run again at five different energies in 2021 to test the new gas-filled separator at Dubna's SHE-factory. They detected 6 chains of 289 Mc, 58 chains of 288 Mc, and 2 chains of 287 Mc. For the first time the 5n channel was observed with 2 atoms of 286 Mc ...
