Darmstadtium is a radioactive metal represented in the D-Block of the periodic table with the symbol Ds, atomic number 110, atomic mass of 281 g.mol-1, and electron configuration [Rn] 5f146d97s1. It\u2019s assumed that this super-heavy element shares its chemical properties with platinum<\/a>, palladium, and nickel<\/a>.\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/span><\/p>\n\n\n\n

How Was Darmstadtium Discovered?<\/span><\/h2>\n\n\n\n

In the 1990s, the chemical element with an atomic mass of 110 was a subject of interest to several teams of scientists. The teams employed at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, and at the German Gesellschaft f\u00fcr Schwerionenforschung (GSI) in Darmstadt, Germany, were among the first ones who attempted to synthesize this super-heavy radioactive element. Unfortunately, all their efforts were futile.  <\/span><\/p>\n\n\n\n

Shortly after the experimental attempts of the Russian and German teams of scientists, the team at the Lawrence Berkeley National Laboratory (LBNL), California, United States, attempted to follow their example. Led by Albert Ghiorso, the Berkeley team succeeded in producing the darmstadtium-267 isotope by bombarding bismuth<\/a> with cobalt<\/a>. However, they were unable to provide evidence and support their scientific finding. <\/span><\/p>\n\n\n\n

Finally, the first atoms of this highly radioactive metal were first produced at the GSI Helmholtz Centre for Heavy Ion Research in 1994. The team of German scientists, led by the nuclear physicists Peter Armbruster (1931), Gottfried M\u00fcnzenberg (1940), and Sigurd Hofmann (1944), attempted to bombard a lead target with nickel-62 ions in a heavy ion accelerator during several consecutive days. <\/span><\/p>\n\n\n\n

The reaction between the lead<\/a> atoms and nickel ions accelerated by a universal linear accelerator helped the team detect a single atom of the isotope darmstadtium-269. Encouraged by this success, the team of scientists later successfully produced nine more atoms of the new synthetic element.\u00a0<\/span><\/p>\n\n\n\n

<\/div>\n\n\n\n

How Did Darmstadtium Get Its Name?<\/span><\/h2>\n\n\n\n

Temporarily named as <\/span>ununnilium <\/span><\/i>(Uun), this chemical element got its name after the city of Darmstadt, Germany, where the element was first produced. The name darmstadtium was proposed by the team who succeeded in producing the first known atoms of this noble metal, in honor of Darmstadt, the location where their revolutionary experiment took place in 1994.\u00a0<\/span><\/p>\n\n\n\n

<\/div>\n\n\n\n

Where Can You Find Darmstadtium?<\/span><\/h2>\n\n\n\n

Being a man-made substance, the elemental form of this chemical element cannot be found free in nature.\u00a0<\/span><\/p>\n\n\n\n

<\/div>\n\n\n\n

Darmstadtium in Everyday Life<\/span><\/h2>\n\n\n\n

Since its properties are yet to be researched and studied, darmstadtium finds its application only in scientific research and experimental chemistry.\u00a0<\/span><\/p>\n\n\n\n

<\/div>\n\n\n\n

How Dangerous Is Darmstadtium?<\/span><\/h2>\n\n\n\n

As a result of the instability of its isotopes, darmstadtium is not yet studied in regard to the effects on human health and has no known biological role.\u00a0<\/span><\/p>\n\n\n\n

<\/div>\n\n\n\n

Environmental Effects of Darmstadtium<\/span><\/h2>\n\n\n\n

Despite being highly radioactive, darmstadtium has no known effect on the environment due to its extremely short half-life.\u00a0<\/span><\/p>\n\n\n\n

<\/div>\n\n\n\n

Isotopes of Darmstadtium<\/span><\/h2>\n\n\n\n

All isotopes of this synthetically produced substance are highly radioactive. Their atomic mass ranges from 279-281, while the half-lives of the isotopes are measured in microseconds. Due to their short lives, the isotopes of darmstadtium undergo spontaneous decay or alpha decay.  <\/span><\/p>\n\n\n\n

Having a half-life of 9.6 seconds, <\/span>darmstadtium-281 is the longest-lived and most stable isotope of darmstadtium. It decays into hassium<\/a>-277 via the emission of alpha-particles or through spontaneous fission. <\/span><\/p>\n\n\n\n
