Hassium [SEP] Introduction
Hassium is a chemical element with the symbol Hs and the atomic number 108. Hassium is highly radioactive; its most stable known isotopes have half-lives of approximately ten seconds. One of its isotopes, Hs, has magic numbers of both protons and neutrons for deformed nuclei, which gives it greater stability against spontaneous fission. Hassium is a superheavy element; it has been produced in a laboratory only in very small quantities by fusing heavy nuclei with lighter ones. Natural occurrences of the element have been hypothesised, but none have ever been found. In the periodic table of elements, hassium is a transactinide element, a member of the 7th period and group8; it is thus the sixth member of the 6d series of transition metals.
