Discovery of Darmstadtium
Darmstadtium was first synthesized by research scientists at the Heavy Ion Research Laboratory in Darmstadt, Germany in 1994.
Four atoms of darmstadtium were produced in the first experiment.
The element is named after the city where it was first made.
In addition to darmstadtium, the Heavy Ion Research Laboratory has been responsible for the discovery of several heavy elements: bohrium in 1981, meitnerium in 1982, hassium in 1984, roentgenium in 1994, and copernicium in 1996.
