Meitnerium was discovered by the same team of German researchers who isolated hassium and Bohrium. |
It was named after Austrian physicist Lise Meitner, who is one of the first to discover nuclear fission. |
As there were no other suggested names for element 109, there was no ensuing dispute over the name. |
Peter Armbruster, Gottfried Munzenberg, and their team synthesized the element in 1982 at their lab in Darmstadt, Germany. |
In order to synthesize the first atom of meitnerium, researchers bombarded an isotope of bismuth, Bi-209, with an isotope of iron, Fe-58. |
The result was a single atom of meitnerium's isotope, Mt-266. |
The isotope they synthesized has an atomic mass that is 266 times heavier than hydrogen. |
While not found in nature due to its rate of decay, there are no primordial samples of meitnerium on Earth. |
The element is a d-block member of the transactinides. |
Its position on the periodic table puts it in the seventh period, and a member of the group nine elements. |
The lack of sample size has prevented researchers from discovering more of meitnerium's chemical and physical properties. |
Based on the properties of surrounding elements on the table, meitnerium is believed to behave like its lighter homologous element, iridium. |
It should have similar properties based on its position on the periodic table to cobalt, rhodium, and iridium. |
There are no stable or natural isotopes for meitnerium. |
Radioactive isotopes of meitnerium have been produced in laboratory conditions. |
These isotopes have occurred through intentional fusion of two atoms, or through the observable decay of other elements. |
There are fifteen recognized radioactive isotopes for meitnerium, eight of which have atomic masses of 266 to 278. |
Meitnerium's heavier isotopes are more stable than its lighter isotopes. |
These isotopes have half-lives that are believed to range from as long as six minutes to as short as 1.7 milliseconds. |
