The team of Russian scientists from Joint Institute for Nuclear Research (JINR) located at Dubna and American scientists from Lawrence Livermore National Laboratory (LLNL) published the report related to this unnamed element. This USA-Russia collaborative experiment strengthens the claim of the discovery of ununpentium and brought the findings of this element. The joint effort on the chemical experiments on the final decay product 268Db yielded results and claims of the existence of ununpentium was established as no nuclides in the decay chain were observed or determined prior this joint experiment and there were no experimental data available to establish the claim.
Ununpentium is a radioactive element, which is discovered jointly by scientist from Russia and USA. Though this metal was discovered in August 2003 and announcement of its existence was made in February 2004, details about this element are not yet completely known. It is the second lightest element, which has not been named as yet.
