Darmstadtium Facts

Darmstadtium Facts
Darmstadtium (Ds) has an atomic number of 110, and therefore has 110 protons in the nucleus of one of its atoms. It was discovered in Darmstadt, Germany, but there are no naturally occurring or primordial samples of the element on Earth.
Interesting Darmstadtium Facts:
Darmstadtium is one of the most recently discovered elements, synthesized in a German laboratory on November 9, 1994.
A team of German researchers led by the scientists who discovered elements 107 through 109 isolated a one-atom sample of darmstadtium.
Elements 111 and 112 have since been discovered at the same lab.
Prior to its official discovery, darmstadtium's place on the periodic table was held with the placeholder name of ununnilium (Uun).
Its current name was officially assigned in 2003 by the IUPAC.
In order to synthesize one atom of the element, researchers fired countless billions of nickel atoms at a lead target over the course of several days.
This process has resulted in only a few atoms of the element ever being produced.
Due to the half-life of only 270 microseconds, observable samples of darmstadtium have not been produced.
In order to understand its properties, scientists have had to rely on its position on the periodic table to make assumptions about its chemical and physical behavior.
As a d-block transactinide element, darmstadtium is a member of the group ten elements in is in the seventh period.
It hasn't been confirmed, but it is believed that darmstadtium is homologous to platinum in its behavior.
It is believed to have somewhat similar properties to nickel, palladium, and platinum.
There are no stable isotopes of darmstadtium, but a number of radioactive isotopes have been discovered.
Like elements similar to it in atomic number, radioactive isotopes of darmstadtium are isolated through fusion of two atoms of different elements, or through the observable decay of heavier elements.
All of darmstadtium's radioactive isotopes are highly unstable, with the most stable having a half-life of only eleven seconds.
Other isotopes have half-lives measured in microseconds.
