| 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. |
