1. Meitnerium

   Meitnerium is a synthetic chemical element with the symbol Mt and atomic number 109. It is an extremely radioactive synthetic element (an element not found in nature, but can be created in a laboratory). The most stable known isotope, meitnerium-278, has a half-life of 4.5 seconds, although the unconfirmed meitnerium-282 may have a longer half-life of 67 seconds. The GSI Helmholtz Centre for Heavy Ion Research near Darmstadt, Germany, first created this element in 1982. It is named after Lise Meitner. In the periodic table, meitnerium is a d-block transactinide element. It is a member of the 7th period and is placed in the group 9 elements, although no chemical experiments have yet been carried out to confirm that it behaves as the heavier homologue to iridium in group 9 as the seventh member of the 6d series of transition metals. Meitnerium is calculated to have similar properties to its lighter homologues, cobalt, rhodium, and iridium.

1. meitnerium

   Meitnerium is a synthetic chemical element with the symbol Mt and atomic number 109. It is an extremely radioactive metal, and it’s considered a synthetic element as it is not found naturally and very few atoms of it have been produced. It was first synthesized in 1982 by a team of scientists in the Laboratory for Heavy Ion Research in Germany. The element was named in honor of physicist and mathematician Lise Meitner. Currently, Meitnerium has no known uses outside of basic scientific research due to its scarcity and instability.
