History

November 9, 1994 at 4:39 pm, the first atom with atomic number 110 was detected at the Gesellschaft fur Schwerionenforschung (GSI) in Darmstadt, in Germany.

Element 110 was produced by fusing a nickel and lead atom together. This was achieved by accelerating the nickel atoms to a high energy in the heavy ion accelerator."This rare reaction occurs only at a very specific velocity of the nickel projectile. Over a period of many days, many billion billion nickel atoms must be shot at a lead target in order to produce and identify a single atom of element 110. The atoms produced in the nickel-lead collisions are selected by a velocity filter and then captured in a detector system which measures their decay. The energy of the emitted helium nuclei serves to identify the atom" (Press Release). This element was only found to have a lifetime of less than 1/1000th of a second. It is expected that soon a heavier version of element 110 that might be more stable, and that lives slightly longer will be developed.

The name darmstatdium was confirmed by IUPAC in August 2003.
