Nihonium
Pronounced
nih-HOH-nee-əm
Nihonium (Nh) is a radioactive metal that has the atomic number 112 in the periodic table, its appearance is not fully known due to the minuscule amounts produced of it. It is in Group 13. It has the symbol Nh.
Nihonium was discovered in 2012 by Kosuke Morita and his team in Japan. It was the first ever chemical element to be discovered in Asia. Using a linear accelerator in Wako, Japan the isotope was isolated but with a half life of a thousandth of a second.
