Facts about Darmstadtium

While studying the periodic table, you can find that among 118 elements that have been found yet, 92 are obtained naturally on this planet. The rest 26 are known as transuranic elements. Any element in this periodic table with an atomic number beyond 92 belongs to this group. Thus, darmstadtium is also a transuranic metal.

These substances are highly unstable and also radioactively decay into different elements. These are the most common characteristics of transuranic elements. Their half-lives can vary from millions of years to fractions of one second. 

In this content, you will learn about darmstadtium or Ds chemistry chapter – its properties, compounds, applications. 

Ds Element

Darmstadtium or Ds element is an artificially produced element with an atomic number of 110. Thus, it is also termed as element 110 in chemistry. Ds signifies its chemical symbol in the periodic table. This element is highly radioactive and not abundant in nature.

The longest stable isotope of darmstadtium is Ds – 281 with a half-life of near about 12.7 seconds. Ds was first ever produced by Sigurd Hofmann, Gottfried Münzenberg, and Peter Armbruster in 1994. This incident took place in Germany - at the Institute for Heavy Ion Research (Gesellschaft für Schwerionenforschung) in Darmstadt. 

Ds was produced by bombarding nickel – 62 atoms with lead – 208 atoms inside a heavy ion accelerator. 

As it was found out near the city of Darmstadt, the element was named Darmstadtium. This substance has some distinguished physical and chemical properties.

As said earlier, this metal was first created in 1994 at the Institute for Heavy Ion Research. During that time, the reaction was conducted by bombarding accelerated nuclei of nickel – 62 towards lead-208 atoms in a heavy-ion accelerator. Through this reaction, the team identified one single atom of darmstadtium isotope – Ds – 269.

Pb-208 + Ni-62 🡪 Ds-269 + 10n

In this similar experiment series, a heavier nickel ion Ni – 64 was used, and after two runs, the team was able to identify nine atoms of Ds – 271.

Darmstadtium Applications

As you have learnt that Ds element is highly unstable. It is a synthetic radioactive metal which means it is not available in nature. Because of its instability, it is difficult to accumulate information about this metal. However, scientists are performing several types of research in various places over the world regading darmstadtium uses.

Presently, darmstadtium is only utilised for scientific research purposes. Also, its biological applications and role are unknown. As it cannot last more than a few seconds, the toxicity level is also yet to be studied.

Effect to the Environment

Similar to the previous point, it transfers to another element within a few seconds as it has a short life span. Thus, it cannot cause any harm to the environment.

Facts about Darmstadtium

  • Darmstadtium is a synthetic or human-made element. Till date, only a few numbers of Ds atoms have been generated. The reaction of lead and nickel was conducted in a heavy-ion accelerator to produce it.
