Darmstadtium is a synthetic chemical element; it has symbol Ds and atomic number 110. It is extremely radioactive: the most stable known isotope, darmstadtium-281, has a half-life of approximately 14 seconds.

Unbinilium, also known as eka-radium or element 120, is a hypothetical chemical element; it has symbol Ubn and atomic number 120. Unbinilium and Ubn are the temporary systematic IUPAC …

There, at element 110 beneath platinum, is the clumsy and practically unpronounceable ununnilium - just a fancy way of saying 'one one oh - ium'. A range of artificial elements were originally given placeholder names like this back in 1979 by the International Union of Pure and Applied Chemistry, the body that controls the naming of chemical ...

Darmstadtium is a chemical element. It has been named ununnilium (Uun) or eka-platinum but is now named darmstadtium. It has the symbol Ds. It has the atomic number 110. It is a transuranium element. The element is named in honor of German city Darmstadt. Darmstadtium is a radioactive element that does not exist in nature. It has to be made.

It was known by the name ununnilium (un-one; un-one; nil-zero; ium-the standard prefix for all elements) before getting its official name [9, 12]. An atomic weight of 281 has earned it the epithet of a super-heavy atom.

darmstadtium (Ds), artificially produced transuranium element of atomic number 110. In 1995 scientists at the Institute for Heavy Ion Research (Gesellschaft für Schwerionenforschung [GSI]) in Darmstadt, Germany, announced the formation of atoms of element 110 when lead -208 was fused with nickel -62.
