Livermorium Facts - Element 116 or Lv

Livermorium Facts - Element 116 or Lv Livermorium (Lv) is element 116 on the periodic table of the elements. Livermorium is a highly radioactive man-made element (not observed in nature). Heres a collection of interesting facts about element 116, as well as a look at its history, properties, and uses: Interesting Livermorium Facts Livermorium was first produced in July 19, 2000 by scientists working jointly at the Lawrence Livermore National Laboratory (USA) and Joint Institute for Nuclear Research (Dubna, Russia). At the Dubna facility, a single atom of livermorium-293 was observed from bombarding a curium-248 target with calcium-48 ions. The element 116 atom decayed into flerovium-289, via alpha decay.Researchers at Lawrence Livermore had announced synthesis of element 116 in 1999, by fusing krypton-86 and lead-208 nuclei to form ununoctium-293 (element 118), which decayed into livermorium-289. However, they retracted the discovery after no one (including themselves) was able to replicate the result. In fact, in 2002, the lab announced the discovery had been based on fabricated data attributed to the principal author, Victor Ninov.Element 116 was called eka-polonium, using Mendeleevs naming convention for unverified elements, or ununhexium (Uuh), using the IUPAC naming convention. Once a new elements synthes is is verified, the discoverers get the right to give it a name. The Dubna group wanted to name element 116 moscovium, after the Moscow Oblast, where Dubna is situated. The Lawrence Livermore team wanted the name livermorium (Lv), which recognizes Lawrence Livermore National Laboratory and Livermore, California, where it is located. The city is named, in turn, for American rancher Robert Livermore, so he indirectly got an element named after him. The IUPAC approved the name livermorium on May 23, 2012. Should researchers ever synthesize enough of element 116 to observe it, its likely livermorium would be a solid metal at room temperature. Based on its position on the periodic table, the element should display chemical properties similar to those of its homologous element, polonium. Some of these chemical properties are also shared by oxygen, sulfur, selenium, and tellurium. Based on its physical and atomic data, livermorium is expected to favor the 2 oxidation state, although some activity of the 4 oxidation state may occur. The 6 oxidation state is not expected to occur at all. Livermorium is expected to have a higher melting point than polonium, yet a lower boiling point. Livermorium is expected to have a higher density than polonium.Livermorium is near an island of nuclear stability, centered on copernicium (element 112) and flerovium (element 114). Elements within the island of stability decay almost exclusively via alpha decay. Livermorium lacks the neutrons to truly be on the island, yet its heavier isotopes decay more slowly than its lighter ones. The molecule livermorane (LvH2) would be the heaviest homolog of water.

Livermorium Sources: Superheavy elements, such as element 116, are the result of nuclear fusion. If scientists succeed in forming even heavier elements, livermorium might be seen as a decay product. Toxicity: Livermorium presents a health hazard because of its extreme radioactivity. The element serves no known biological function in any organism. References Fricke, Burkhard (1975).
