Nihonium is a synthetic chemical element; it has symbol Nh and atomic number 113. It is extremely radioactive: its most stable known isotope, nihonium-286, has a half-life of about 10 seconds. In the periodic table, nihonium is a transactinide element in the p-block. It is a member of period 7 and group 13.

Nihonium, formerly known as Ununtrium (Uut), is a p-block transactinide element in the periodic table, with its group number being 13. Nihonium is a highly radioactive metal and is represented by the symbol Nh. It was invented through the bombardment of atoms of Americium-243 with Calcium – 48 ions. Chemical Properties of Nihonium

Extremely radioactive, the atom decayed through emission of alpha particles (helium nuclei) to dubnium -262 in about 2.5 seconds. Its chemical properties may be similar to those of thallium.

Feb 4, 2019 · Get all of the facts on the chemical and physical properties of nihonium, element 113 on the periodic table.

On July 23, 2004, scientists working at the RIKEN Nishina Center for Accelerator-based Science in Wako, Japan, created the first two atoms of the element nihonium by accelerating zinc ions to 10 percent the speed of light and then impacting them onto a thin bismuth target.

It was the first chemical element ever discovered in Asia. The discovery was formally accepted on December 30, 2015 by IUPAC and IUPAP, and a new superheavy element took its place in the seventh row of the periodic table. The element is named after the place it was first synthesized; Nihon is one of two ways to say Japan in Japanese.

Ununtrium (symbol Uut, atomic number 113) is a chemical element with a temporary name which was discovered in 2003 at the Lawrence Livermore National Laboratory and the Joint Institute for Nuclear Research.
