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. The element is named after the Lawrence Livermore National Laboratory in the United States, which collaborated with the Joint Institute for Nuclear Research in Dubna, Russia to discover livermorium during experiments made between 2000 and 2006. The name of the laboratory refers to the city of Livermore, California where it is located, which in turn was named after the rancher and landowner Robert Livermore
Elements 115 and 117, formerly called ununpentium and ununseptium, are now moscovium (Mc) and tennessine (Ts), respectively. The two elements were synthesized by a team of American and Russian scientists and named after the sites of their discovery. Moscovium honors the Joint Institute for Nuclear Research in Dubna outside Moscow, while tennessine recognizes the contributions of Oak Ridge National Laboratory and its surrounding universities in Tennessee.
Element 118, previously known as ununoctium, will be named oganesson (Og). Discovered by the same joint Russian-American team of scientists, the element is named after Yuri Oganessian, a Russian physicist at the Flerov Laboratory and a prominent figure in the international hunt for superheavy elements. Oganesson is the second element named for a living person; the first, seaborgium, was named in 1997 after American physicist Glenn Seaborg two years before his death.
