A Tranuranic element is any element that comes after the element of Uranium in the Periodic Table. They are all radioactive and all but 2 are man made or synthetic (those being Uranium and Plutonium), and decay into other elements. Everything from Neptunium to Lawrencium to Tennessine and Oganesson. Some elements have no uses in everyday life, those being Fermium onward, but some have few uses, like Uranium being used for fuel and Curium being used in rovers.
