What is Darmstadtium?

  • Darmstadtium (Ds) is a synthetic chemical element with atomic number 110 and symbol Ds in the Periodic Table.
  • It was first created by the Gesellschaft für Schwerionenforschung ( Society for Heavy Ion Research ) in the year 1994. Credit for the discovery goes to Sigurd Hofmann, Peter Armbruster, and Gottfried Münzenberg.
  • The discovery was near a City called Darmstadt, Germany and this is the reason it was named Darmstadtium.

Uses of Darmstadtium

  • Presently, there are no uses or applications of Darmstadtium. It is only used for research purposes. Biological use is yet to be known.

Properties of Darmstadtium

  • It is a man-made element of which only a few atoms have ever been created. It was created in a heavy ion accelerator using atoms of lead & nickel. Thus, most of its properties have been predicted.
  • It is a d-block transactinide element in the periodic table and a member of the 7th period which is placed in group 10 elements.
  • It was predicted that this element contains similar properties as that of its homologues, palladium, nickel, and platinum.
  • The element has no naturally occurring or stable isotopes. The most stable known isotope is darmstadtium whose life is expected be approximately 10 seconds.
  • Darmstadtium is expected to be solid at room temperature and a very heavy metal with a density of 34.8 g/cm3

Environment Effects of Darmstadtium

  • These elements have very unstable nuclei and it does not occur naturally in nature. Due to its short life, it is not harmful to the environment.

Practise This Question

In each of the following question, an Assertion (A) is followed by a corresponding Reason (R). Use the following keys to choose the appropriate answer: 

Assertion (A): There is a natural asymmetry between converting work to heat and converting heat to work. 
Reason (R): No process is possible in which the sole result is the absorption of heat from a reservoir and its complete conversion into work.
