About Livermorium

Livermorium Bohr

Livermorium (formerly known as Ununhexium, symbol: Uuh) is a synthetic superheavy element first produced in 2000 by the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. A team from Lawrence Livermore National Laboratory also worked on the element, and though they gave credit to the JINR group for the discovery, the IUPAC rejected the name moscovium for the element in favor of recognizing the Lawrence Livermore laboratory with the element's name. To date, very few atoms of livermorium have been produced, precluding both in-depth study of the element's properties and well as the development of practical applications for it. As the heaviest member of group 16 in the periodic table, livermorium would likely exhibit similar chemical properties to other members of this group, showing the most similarity to its nearest neighbor, polonium.
