What is Meitnerium?
- Meitnerium (Mt) is a synthetic chemical element with atomic number 109 and symbol Mt in the periodic table. It was first created by a German Research team lead by Gottfried Munzenberg and Peter Armbruster at Gesellschaft fur Schwerionenforschung in the year 1982.
- Meitnerium is a D-block transactinide element, which is a member of the 7th period and arranged in the group 9 elements in the periodic table. It is predicted to have similar properties as that of its lighter homologous, rhodium, cobalt, and iridium.
- Meitnerium does not possess any naturally occurring or stable isotopes. Many radioactive isotopes have been made in the laboratory, either by observing the decay of heavier metals or by fusing two atoms.
- These kinds of elements are always prepared artificially as they never occur naturally in the Earth’s Crust. As it can never present in the Earth’s crust, there is no need to worry about health effects of it.
Uses of Meitnerium
- Presently, there are no uses or applications except that it is used for research.
