Who discovered meitnerium 109?
Background. Meitnerium was first discovered by Gottfried Münzenber and Peter Armbruster at Heavy Ion Research Laboratory in Darmstadt, Germany in 1982. They bombarded bismuth-209 atoms with iron-58 ions in a linear accelerator and produced meitnerium-266 atoms with free neutrons.
Where can meitnerium be found?
Darmstadt
Discovery: The element was discovered in Darmstadt, Germany, in 1982 at Heavy Ion Laboratory. The team of Peter Armbruster and Gottfried Münzenber first produced and identified it.

How is meitnerium used in research?
It has an atomic number of 109 and an atomic mass of 268 AMU. It is considered a transition metal and is radioactive. Currently, there are no real uses for meitnerium, except in research. In time, meitnerium might be used for technology purposes and harvesting energy.
What is the family name for meitnerium?
transuranium group
meitnerium (Mt), an artificially produced element belonging to the transuranium group, atomic number 109. It is predicted to have chemical properties resembling those of iridium. The element is named in honour of Austrian-born physicist Lise Meitner.
When was the element meitnerium discovered?

Which element is RG?
roentgenium
roentgenium (Rg), artificially produced transuranium element of atomic number 111.
When was the element Meitnerium discovered?
Why is Meitnerium useful?
It is considered a transition metal and is radioactive. Currently, there are no real uses for meitnerium, except in research. In time, meitnerium might be used for technology purposes and harvesting energy.
What is the history of meitnerium?
Discovery of Meitnerium. Meitnerium was first synthesized by research scientists led by Peter Armbruster and Gottfried Münzenber at the Heavy Ion Research Laboratory in Darmstadt, Germany in 1982. Meitnerium was produced when bismuth-209 was bombarded with accelerated iron-58 nuclei. The element was named after physicist Lise Meitner.
Why is the element named after Lise Meitner?
The only name proposed for the discovered element was “meitnerium” (Mt), in honor of Austrian physicist Lise Meitner, who was one of the discoverers of nuclear fission and the co-discoverer of the element protactinium (together with Otto Hahn). The name was recommended to the IUPAC in 1994 and formally adopted in 1997.
What was the original name of the element discovered in 1994?
The only name proposed for the discovered element was “meitnerium” (Mt), in honor of Austrian physicist Lise Meitner, who was one of the discoverers of nuclear fission and the co-discoverer of the element protactinium (together with Otto Hahn). The name was recommended to the IUPAC in 1994…
What are the physical and chemical properties of meitnerium?
Meitnerium is a solid, radioactive metal at room temperature. Very little is known about its physical and chemical properties, but based on trends in the periodic table, it is believed to behave as a transition metal, like the other actinide elements. Meitnerium is expected to possess properties similar to its lighter homologous element, iridium.
