Posted by on Sunday, January 3, 2016

A team of scientists based at the Riken Nishina Centre for Accelerator-Based Science has been given the go-ahead for naming a new element, the synthetic highly radioactive element 113.

The decision came Thursday from the International Union of Pure and Applied Chemistry.

They have been working for more than 12 years to create it.

The new name for element 113 may be japonium the current name for it is ununtrium.

Both Russian and U.S. scientists were also seeking 113.

Ununtrium is a chemical element with atomic number 113. It has a temporary name and temporary symbol Uut. It is an extremely radioactive synthetic element; its most stable known isotope, ununtrium-286, has a half-life of 20 seconds.
