Darmstadtium (formerly ununnilium or Eka-Platinum) is a chemical element in the periodic table that has the symbol Ds and atomic number 110, making it one of the super-heavy atoms. It is a synthetic element and quickly decays; its isotopes of mass 267 to 273 have half-lives measured in microseconds. However, heavier isotopes of mass 280 and 281 have been synthesized recently which are more stable, with half-lives of 7.6 s and 1.1 min, respectively. ...
