Darmstadtium

Darmstadtium (formerly Ununnilium) is a chemical element in the periodic table that has the symbol Ds and atomic number 110. It has an atomic weight of 271 making it one of the super-heavy atoms[?]. It is a synthetic element and decays in thousandths of a second. Due to its presence in Group 10 it is believed to be likely to be metallic and solid.

History It was first created on November 9, 1994 at the Gesellschaft für Schwerionenforschung (GSI[?]) in Darmstadt, Germany. It has never been seen and only a few atoms of it have been created by the nuclear fusion of isotopes of lead and nickel in a heavy ion accelerator[?] (nickel atoms are the ones accelerated and bombarded into the lead).

Scientists are not always serious, so some suggested the name policium for the new element, because 110 is the telephone number of the German police. The element was named after the places of its discovery, Darmstadt (actually, the GSI is located in Wixhausen, a small suburb north of Darmstadt). The new name was given to it by the IUPAC in May 2003.
