Say what? Darmstadtium is pronounced as darm-STADT-i-em.
History and Uses:
Darmstadtium was first produced by Peter Armbruster, Gottfried Münzenber and their team working at the Gesellschaft für Schwerionenforschung in Darmstadt, Germany on November 9th, 1994. They bombarded atoms of lead with ions of nickel with a device known as a linear accelerator. This produced one atom of darmstadtium-269, an isotope with a half-life of about 0.17 milliseconds (0.00017 seconds), after at least a billion billion (1,000,000,000,000,000,000) nickel ions were fired at the lead target over the course of a week.
Darmstadtium's most stable isotope, darmstadtium-281, has a half-life of about 1.1 minutes. It decays into hassium-277 through alpha decay.
Since only a few atoms of darmstadtium have ever been produced, it currently has no uses outside of basic scientific research.
