Darmstadtium

Darmstadtium is a synthetic chemical element; it has symbol Ds and atomic number 110. It is named after the city of Darmstadt, Germany, where the GSI Helmholtz Centre for Heavy Ion Research is located. Darmstadtium was first created in November 1994 by a team led by Sigurd Hofmann at GSI. It is extremely radioactive; its most stable known isotope, darmstadtium-281, has a half-life of approximately 14 seconds. It has no known practical applications.

Main Uses of the Element

Darmstadtium is the 110th superheavy element, first synthesized in 1994 by the GSI team in Germany by bombarding lead-208 with nickel-62 ions, and named after the German city of Darmstadt. Its isotopes have extremely short half-lives, it does not occur in nature, and only a few atoms are produced per synthesis. It has no industrial uses and is studied only for nuclear properties and relativistic effects.

Key Compounds and Their Uses

The chemical behavior of darmstadtium has been investigated only in single-atom experiments, suggesting possible platinum-group-metal-like properties. No weighable darmstadtium compound has ever been isolated, and no practical applications exist.

Element History

Discovered in 1994 at GSI Darmstadt by Armbruster and Münzenberg via bombardment of lead-208 with nickel-62 ions — darmstadtium-269 was identified. Named for Darmstadt, the location of GSI. Ds-271 (1.7 h half-life, discovered 2002) is the longest-lived isotope.
