Livermorium is the seenthetic superhivy element wi the seembol Lv an atomic nummer 116. The name wis adoptit bi IUPAC on Mey 30, 2012.[3]

It is placed as the hiviest member o groop 16 (VIA) altho a sufficiently stable isotope is nae kent at this time tae allae chemical experiments tae confirm its poseetion as a hivier homologue tae polonium.

It wis first detectit in 2000. Syne then, aboot 35 atoms o livermorium hae been produced, either directly or as a decay product o ununoctium, belangin tae the fower neighbouring isotopes wi masses 290–293. The maist stable isotope kent is livermorium-293 wi a hauf-life o ~60 ms.
