History

Darmstadtium was nuclear fusion reaction caused by bombarding a lead target with nickel:[1]

\,^{208}_{82}\mathrm{Pb} + \,^{62}_{28}\mathrm{Ni} \, \to \,^{269}_{110}\mathrm{Ds} + \; ^1_0\mathrm{n} \;

The element was named after the place of its discovery, Darmstadt. The new name was given to it by the IUPAC on August 16, 2003.

Because the telephone number of the police is 110 within Germany, the element has also earned the nickname of "policium".
