Darmstadtium is a chemical element with the symbol Ds and atomic number 110. It is placed as the heaviest member of group 10, but no known isotope is sufficiently stable to allow chemical experiments to confirm its placing in that group as a heavier homologue to platinum. This synthetic element is one of the so-called super-heavy atoms and was first synthesized in 1994, at a facility near the city of Darmstadt, Germany, from which it takes its name. The longest-lived and heaviest isotope known is 281aDs with a half-life of ~10 s although a possible nuclear isomer, 281bDs has an unconfirmed half-life of about 4 minutes.
