Trans-uranium elements are elements with atomic numbers greater than 92, which is the atomic number of Uranium. The heaviest naturally occurring element is Uranium. The elements with atomic numbers greater than 92 are made in the laboratory by capture of neutrons. These elements have not been observed to occur in natural state, or in the form of ores on Earth.
Therefore, one can conclude that all elements with atomic numbers greater than 92 and occurring in the periodic table after Uranium must have been created in the laboratory alone.
