Also known as Hs, element 108, unniloctium, Uno

Hassium is a synthetic chemical element; it has symbol Hs and atomic number 108. It is highly radioactive: its most stable known isotopes have half-lives of about ten seconds. One of its isotopes, Hs, has magic numbers of protons and neutrons for deformed nuclei, giving it greater stability against spontaneous fission. Hassium is a superheavy element; it has been produced in a laboratory in very small quantities by fusing heavy nuclei with lighter ones. Natural occurrences of hassium have been hypothesized but never found.

AI overview

Hassium is a synthetic chemical element (atomic number 108) that scientists create in laboratories by fusing heavy nuclei together, and it is extremely radioactive with isotopes that decay in just seconds. It matters to nuclear physics research because one of its isotopes has a special nuclear structure that makes it more stable than expected, helping scientists understand the properties of superheavy elements.
