Nihonium

Nihonium is element 113. A team led by Kosuke Morita at the RIKEN institute near Tokyo spent about nine years firing zinc nuclei at a bismuth target. They detected just three atoms, in 2004, 2005 and 2012. In 2016 it was named after Japan, Nihon in Japanese, making it the first element discovered in Asia.

A Russian–American team in Dubna had also seen nihonium forming as moscovium decayed. Depending on the form, its atoms last from thousandths of a second to several seconds. It sits below thallium and is predicted to be a heavy metal, but its chemistry has barely been explored.
