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. [a] One of its isotopes, 270 Hs, has magic numbers of protons and neutrons for deformed nuclei, giving it greater stability against spontaneous fission.

Hassium is a synthetic element that was discovered in 1978. It is a highly radioactive and unstable element. According to the Mendeleev’s nomenclature of undiscovered elements, hassium was named as eka-osmium or element-108.

hassium (Hs), an artificially produced element belonging to the transuranium group, atomic number 108. It was synthesized and identified in 1984 by West German researchers at the Institute for Heavy Ion Research (Gesellschaft für Schwerionenforschung [GSI]) in Darmstadt.

2013年10月28日 · Hassium is a synthetic element about which little is known. It is presumed to be a solid metal, but since only a few atoms of it have been created, it is difficult to study. All of its isotopes...
