Meitnerium svg

Meitnerium is a chemical element with the symbol Mt and atomic number 109. It is placed as the heaviest member of group 9 (or VIII) in the periodic table but a sufficiently stable isotope is not known at this time, which would allow chemical experiments to confirm its position, unlike its lighter neighbours. Several isotopes are currently known. The heaviest and the most stable isotope known is Mt-278, with a half-life of ~8 s.


Characteristics Edit

Currently teams are attempting to search for the isotope 271Mt with hope that it may be sufficiently stable to allow a first study of the chemical properties of meitnerium. Unfortunately, no atoms were detected and a cross section limit of 1.5 pb was measured for the 4n channel at the projectile energy used. Isotopes of meitnerium have also been detected in the decay of heavier elements.


ValueEdit

The base value of each unit of ranges between 25 and 75Ð per unit, with up to 7 units being found at any one time.
