Background
Livermorium was discovered in July 2000 at Dubna, Russia. Research teams involved in the discovery of this element include teams from the Lawrence Livermore National Laboratory in California and the Joint Institute for Nuclear Research in Dubna. These two science teams were guided by Ken Moody and Yuri Oganessian. This entire discovery procedure was reviewed for a number or years by the International Union of Pure and Applied Chemistry (IUPAC) and the discovery of livermorium was finally accepted as in 2011.
A single atom of livermorium-292 was first produced followed by the production of two more atoms after almost a year. The first atom existed for 125.5 ms and the second atom for 55.0 ms. A total of 30 atoms of livermorium were produced by 2005.

Isotopes
Livermorium has four isotopes all of which are not stable. These isotopes have half-lives along with mass numbers raging from 290 to 293. 293Lv is the most stable isotope comprising a half-life of about 61 ms.
Production
Livermorium is produced by bombarding atoms of curium-248 with ions of calcium-48. Livermorium-292 and four free neutrons were produced from this bombardment process.
Health Aspects
Livermorium is a harmful element because of its radioactivity.
Key Properties
The key property of livermorium includes:
-
It is a synthetic radioactive metal available only in small quantities.
Applications
Livermorium is currently used only in research.
