Quick answerDarmstadtium (Ds) is a transition metal with atomic number 110 and a mass number of 281 (the most stable isotope), in group 10, period 7. It was discovered by Sigurd Hofmann and colleagues in 1994. It is used for superheavy element research and studying transactinide chemistry. Its electron configuration is [Rn] 5f14 6d8 7s2 (predicted).
Darmstadtium is a synthetic element named for Darmstadt, the German city where it was first created in 1994.
