Japanese scientists who discovered the atomic element 113 named it "nihonium". 
The team of researchers at Riken institute coined the name from "Nihon," meaning Japan in Japanese, and gave the superheavy synthetic element the atomic symbol "Nh." The team, led by Kyushu University professor Kosuke Morita, secured the naming rights in December after creating the element three times in 2004, 2005 and 2012. 
Morita proposed the name to the IUPAC in March for review. After the announcement, the organization is expected to invite public comments on the name before formally deciding around the end of the year. 
The element has 113 protons in its nucleus. Morita’s group created the element by colliding zinc ions with bismuth, which have 30 protons and 83 protons, respectively.
