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.

nihonium (Nh), artificially produced transuranium element of atomic number 113. In 2004 scientists at the RIKEN Nishina Center for Accelerator-Based Science in Saitama, Japan announced the production of one atom of element 113, which was formed when bismuth-209 was fused with zinc-70.

Nihonium. Nihonium is a chemical element with symbol Nh and atomic number 113. Classified as a post-transition metal, Nihonium is a expected to be a solid at room temperature.

Nov 5, 2024 · Nihonium (Nh) is an artificial element with atomic number 113. As a superheavy, radioactive metal , nihonium exists only in the laboratory, where it is produced through particle collisions in nuclear reactors.

Mar 9, 2024 · Nihonium is a synthetic transition metal with an atomic number of 113 and is represented by the symbol ‘Nh’ in the periodic table. It is silvery in appearance and belongs to the p-block of period 7 of the periodic table.

What is Nihonium. Nihonium (pronunciation nee-hone-ee-em [2]), represented by the chemical symbol Nh, is a synthetic, radioactive, transuranium metal [1, 10, 11]. Of its two known isotopes, Nh 284 and Nh 286 [1], the latter is more stable with a half-life of 20 seconds [2].

Dec 2, 2016 · Nihonium is a radioactive, synthetic element about which little is known. It is classified as a metal and is expected to be solid at room temperature.

Jan 21, 2025 · Nihonium is a synthetic chemical element with the symbol Nh and atomic number 113. It belongs to the group of elements known as the post-transition metals in the periodic table.

Feb 4, 2019 · Nihonium is a radioactive synthetic element with the symbol Nh and atomic number 113. Because of its position on the periodic table, the element is expected to be a solid metal at room temperature. The discovery of element 113 was made official in 2016. To date, few atoms of the element have been produced, so little is known about its properties.
