A radioactive transactinide; a.n. 110. It has several isotopes; the most stable being 281Ds, with a half-life of about 1.6 minutes. It can be produced by bombarding a plutonium target with sulphur nuclei or by bombarding a lead target with nickel nuclei. Its chemical properties probably resemble those of platinum. Darmstadtium was named after the German city of Darmstadt, the location of the Institute for Heavy Ion Research where it was first produced in 1994 by Peter Armbruster and his colleagues.
