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.

AI overview

Nihonium is a human-made chemical element (symbol Nh, atomic number 113) that is extremely radioactive and breaks down very quickly, with its most stable form lasting only about 10 seconds before decaying. Scientists study it as part of their exploration of the periodic table's heaviest elements, though its extreme instability makes it difficult to observe and use in practical applications.
