Livermorium does not occur in nature, and was first made in the year 2000, at the Joint Institute for Nuclear Research, in Dubna, Russian. It was made by firing calcium nucleii at a target of curium metal. Livermorium is named after the Lawrence Livermore National Laboratory (LLNL) because it was the LLNL who supplied the curium target that was used. Livermorium is a radioactive metal, and its longest lived isotope has a half life of only 0.061 seconds!
