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.
