The periodic table has created and detected the element corresponding to position 117 at the Russian nuclear research institute JINR. In recent years, this institute has been the entity that has generated more elements, since in it they were created from element 113 to 118, with the exception of 117. In the end they have also achieved their formation by throwing the ions calcium 48 against an isotope of the berquelio element. For five months there were constant collisions that allowed detecting six atoms of element 117 among all the resulting atoms. For the moment they have called him ununseptium, the Latin of number 117.
