Four elements, currently known by the Latin name for their atomic numbers – ununtrium (113), ununpentium (115), ununseptium (117) and ununoctium (118) – completed the seventh row of the periodic table when the chemistry organisation verified their discoveries at the end of December last year.
The International Union of Pure and Applied Chemistry, which rules on chemical element names, said that the names will pay tribute to Japan, Moscow, Tennessee and a Russian scientist. The names moscovium, nihonium, tennessine and oganesson, submitted by the element discoverers were presented on Wednesday for public review.
Moscovium, symbol Mc, for element 115, and Tennessine, symbol Ts, for element 117. The discovery team is from the Joint Institute for Nuclear Research in Dubna, Russia, the Oak Ridge National Laboratory and Vanderbilt University in Tennessee, and the Lawrence Livermore National Laboratory in California.
Nihonium, symbol Nh, for element 113. The element was discovered in Japan, and Nihon is one way to say the country’s name in Japanese. It is the first element to be discovered in an Asian country.
Oganesson, symbol Og, for element 118. The name honours Russian physicist Yuri Oganessian.
The four elements are not found in nature, and were synthetically created in laboratories. These elements till now had temporary names and symbols as their existence was hard to prove since they decay extremely quickly and scientists found it difficult to reproduce them.
The public comment period will end on 8 November.
