Livermorium (Lv)

Livermorium is a synthetic and highly radioactive element located at position 116 in the periodic table. It was first discovered in 2000 and named after the Lawrence Livermore National Laboratory in the United States. Most of its properties are based on observations of the extremely small number of atoms produced to date and theoretical calculations.

Classification and Fundamental Properties

Livermorium (Lv) is an element in period 7 and group 16 (the chalcogen group) of the periodic table. Its expected electron configuration is [Rn] 5f¹⁴6d¹⁰7s²7p⁴. It is considered a heavier homologue of polonium based on its electronic structure. Theoretical calculations predict that livermorium will behave like a post-transition metal and exist as a solid at room temperature.

Discovery

Livermorium was first synthesized in 2000 by a team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna Russia. The discovery team included scientists from the Lawrence Livermore National Laboratory (LLNL) in the United States.

The element was produced by bombarding curium-248 (²⁴⁸Cm) targets with calcium-48 (⁴⁸Ca) ions. In these experiments, one atom of livermorium-293 (²⁹³Lv) and its alpha decay products were observed. The discovery was officially recognized in 2011 by the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP), and the name was assigned in 2012.

Etiology

The name livermorium honors the Lawrence Livermore National Laboratory (LLNL) in California and the city of Livermore where the laboratory is located, both of which played a significant role in its discovery.

Natural Occurrence

Livermorium is a completely synthetic element and does not occur naturally. It can only be produced in minute quantities under laboratory conditions through nuclear reactions in particle accelerators. To date, only a few atoms have been successfully synthesized and observed.

Physical and Chemical Properties

Information on the physical and chemical properties of livermorium is extremely limited and largely based on theoretical models. It is predicted to be a solid metal at room temperature, but no experimental data exists regarding its appearance. Thermal properties such as density melting point and boiling point have not yet been determined experimentally.

Chemically, it is expected to exhibit behavior similar to other chalcogens in its group (such as oxygen sulfur selenium tellurium and polonium); however it is predicted to show more pronounced metallic character. The most stable oxidation states of livermorium are theoretically predicted to be +2 and +4 while the -2 state is considered less stable. The atomic weight of its longest-lived isotope ²⁹³Lv is approximately 293 g/mol.

Isotopes

Livermorium has four known isotopes all of which are highly radioactive and unstable. The known isotopes are ²⁹⁰Lv ²⁹¹Lv ²⁹²Lv and ²⁹³Lv.

• ²⁹³Lv: The most stable known isotope with a half-life of approximately 53 milliseconds. It decays via alpha emission to form the isotope flerovium-289 (²⁸⁹Fl).

Applications

Due to its extremely short half-life difficulty of production and the minuscule quantities produced (only a few atoms) livermorium has no practical applications beyond fundamental scientific research. Its synthesis is carried out solely to explore the limits of nuclear physics and chemistry study the structure stability and decay characteristics of heavy nuclei.

Biological Role and Precautions

Livermorium has no known biological role. Due to its extreme radioactivity and instability it would be highly hazardous and toxic if sufficient quantities could be produced. However since only a few atoms have ever been synthesized it is practically meaningless to discuss standard biological effects or special precautions. When produced in a laboratory setting standard safety protocols applicable to all radioactive materials are followed.
