The transuranium (or transuranic) elements are the chemical elements with atomic number greater than 92, which is the atomic number of uranium. All of them are radioactively unstable and decay into other elements. Except for neptunium and plutonium which have been found in trace amounts in nature, none occur naturally on Earth and they are synthetic.
