Chemical, physical and material properties and data of the chemical element Livermorium.



Livermorium - element symbol: Lv - is the name accepted by the IUPAC in May 2012 for the artificial chemical element 116 (systematic name: Ununhexium, Uuh).

The name was chosen in honor of the city of Livermore and the home of the Lawrence Livermore National Laboratory (see also: discovery of flerovium and livermorium).
