Element 113, known as Nihonium, is a synthetic element that was officially recognized in 2016. It is represented by the symbol Nh and has an atomic number of 113. Nihonium is part of the p-block of the periodic table and belongs to the group of post-transition metals. Due to its short half-life, Nihonium is highly unstable and has only been produced in minute quantities in laboratories. Its most stable isotope, Nh-286, has a half-life of about 20 milliseconds. Research on Nihonium helps scientists understand the properties of superheavy elements and the limits of the periodic table.
