Livermorium

 

Livermorium is a synthetic chemical element with symbol Lv and atomic number 116. It is an extremely radioactive element that has only been created in the laboratory and has not been observed in nature.
   

Livermorium was first synthesized on July 19, 2000 by a team ofscientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. 
In 2011, IUPAC evaluated the Dubna team experiments of 2000–2006. Whereas they found the earliest data (not involving 291v and 283Cn) inconclusive, the results of 2004–2006 were accepted as identification of livermorium, and the element was officially recognized as having been discovered.
IUPAC Technical Report dated 01.06.2011.
On 23 May 2012, the IUPAC approved the name livermorium, symbol Lv for the element 116.
 
  
Technical Report dated 26.06.2012
Element 114 is named flerovium and element 116 is named livermorium“
