First element discovered in Asia named "nihonium", after Japan

Japanese scientists behind the discovery of element 113, the first atomic element found in Asia - indeed, the first found outside Europe or the United States - have dubbed it "nihonium" after the Japanese-language name for their country.

"I believe the fact that we, in Japan, found one of only 118 known atomic elements gives this discovery great meaning," said Kosuke Morita, a university professor who led the discovery team from the RIKEN Nishina Center for Accelerator-Based Science.

Four new elements added to periodic table

"Another important meaning is that until now, all the elements in the periodic table have been discovered in Europe and the United States," he told a news conference on Thursday.

"There has not been a single atomic element found in Asia, Oceania or Africa."

Element 113 was first found in 2004, and the number refers to its atomic number, or the number of protons in the nucleus of the atom. It does not exist naturally and has had to be synthesized.

Though the element was publicly recognized by the International Union of Pure and Applied Chemistry (IUPAC) in December 2015, the name was not announced by IUPAC until Wednesday. It will become permanent after a five-month public review.

If approved, it will join other newly announced elements: moscovium for element 116, tennessine for element 117 and oganesson for element 118.

It will also not be the only element to be named after a country, having been proceeded by polonium and francium after the places they were discovered.
