Hassium: the essentials

Hassium atoms have 108 electrons and the shell structure is 2.8.18.32.32.14.2. The ground state electronic configuration of neutral hassium is [Rn].5f14.6d6.7s2 (a guess based upon that of osmium) and the term symbol of hassium is 5D4 (a guess based upon guessed electronic structure).

Hassium: description  

Hassium, is a synthetic element that is not present in the environment at all.

The interested reader should consult the on-line version of Creating Super Heavy Elements for a fascinating insight into research on "super-heavy" atoms.

Hassium: history

Hassium was discovered by Peter Armbruster, Gottfried Münzenber and their co-workers. in 1984 at Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany.. Origin of name: the origin of the name is the Latin word "Hassias" meaning "Hess", the German state..

Hassium: isolation

Isolation: only a few atoms of element 108, hassium, have ever been made. The first atoms were made through a nuclear reaction involving fusion of an isotope of lead, 208Pb, with one of iron, 58Fe.

208Bi + 58Fe → 265Hs + 1n

Isolation of an observable quantity of hassium has never been achieved, and may well never be. This is because hassium decays very rapidly through the emission of α-particles.
