Nihonium

nihonio nihomio

Nihonium is named after the Japanese word nihon, meaning Japan. The first metallic element, nihonium, was first detected in 2003 by teams studying the artificial element muscovium. In 2004, Kozuka Morita and a team of scientists at the RIKEN Nuclear Research Center in Japan isolated this element in a different way: they fused atoms of bismuth and zinc.
