Based on this information, several scientists and journalists have called her exclusion "unjust", and Meitner has received a flurry of posthumous honors, including the naming of chemical element 109 as meitnerium in 1997. Source: Internet

The tetrahalides of meitnerium have also been predicted to have similar stabilities to those of iridium, thus also allowing a stable +4 state. Source: Internet

Prediction of the probable chemical properties of meitnerium has not received much attention recently. Source: Internet

Stability and half-lives All meitnerium isotopes are extremely unstable and radioactive; in general, heavier isotopes are more stable than the lighter. Source: Internet

The most stable known meitnerium isotope, 278 Mt, is also the heaviest known; it has a half-life of 7.6 seconds. Source: Internet

The naming of meitnerium was discussed in the element naming controversy regarding the names of elements 104 to 109, but meitnerium was the only proposal and thus was never disputed. Source: Internet
