Hassium: the essentials

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

The interested reader should consult the on-line version of The Wonderful World of Atoms and Nuclei for a fascinating insight into research on "super-heavy" atoms.

Hassium: historical information

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 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).

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.
