Darmstadtium: the essentials

Darmstadtium atoms have 110 electrons and the shell structure is 2.8.18.32.32.17.1. The ground state electronic configuration of neutral darmstadtium is [Rn].5f14.6d9.7s1 (a guess based upon that of platinum) and the term symbol of darmstadtium is 3D3 (a guess based upon guessed electronic structure).

Darmstadtium: description  

Darmstadtium, is a synthetic element that is not present in the environment at all. The interested reader should consult the on-line version of Creating Super Heavy Elements for a fascinating insight into research on "super-heavy" atoms.

Chemically, darmstadtium is in the same Group as nickel, palladium, and platinum (Group 10). Unlike these lighter atoms, darmstadtium decays after a small fraction of a thousandth of a second into lighter elements by emitting α-particles which are the nuclei of helium atoms.

Darmstadtium: history

Darmstadtium was discovered by S. Hofmann, V. Ninov, F. P. Hessberger, P. Armbruster, H. Folger, G. Münzenberg, H. J. Schött, and others in 1994 at Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany.. Origin of name: the name darmstadtium lies within the long established tradition of naming an element after the place of its discovery, Darmstadt, in Germany..

Darmstadtium: isolation

Isolation: only a few atoms of darmstadtium have ever been made, initially through a nuclear reaction involving fusion of an isotope of lead, Pb, with one of nickel, Ni.

208Pb + 62Ni → 269Ds + 1n

Isolation of an observable quantity has never been achieved, and may well never be. This is because atoms of the element decompose through the emission of α-particles with a half life of only about 270 microseconds. Another isotope was made by using a different isotope of nickel.

208Pb + 64Ni → 271Ds + 1n
