Meitnerium Facts

Meitnerium Facts
Meitnerium (Mt) is a synthetic element with an atomic number of 109. Therefore, the element has 109 protons in the nucleus of one of its atoms. Having being isolated following the Transfermium Wars, there was no dispute over the element's discovery or name.
Interesting Meitnerium Facts:
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.
