Elements named after Japan, Moscow
Print Edition
FOUR new elements have been added to the periodic table after discoveries by Japanese, Russian and American scientists, an international authority said, with the new substances including Asia’s first entry on the chart.
Scientists in Japan who discovered element 113 have opted for nihonium, derived from the name of the country in the local language, and the accompanying symbol Nh.
Russian and US scientists, meanwhile, have proposed moscovium and Mc for element 115, tennessine and Ts for element 117 and oganesson and Og for element 118.
The International Union of Pure and Applied Chemistry has recommended the names and symbols be accepted after a five-month public review, it said on its website.
Synthetic elements are produced through laboratory experiments rather than those found in nature such as hydrogen, carbon or magnesium.
Besides being the first element on the periodic table to be discovered and named by Japanese scientists, element 113 is also Asia’s first, according to Riken, the Japanese state-backed research institute that discovered it, and IUPAC.
“Nippon (Nihon)” is a slightly more formal variant of the country’s name in Japanese.
The other elements are named after the Russian capital Moscow, US state Tennessee and Russian nuclear physicist Yuri Oganessian.
