Answer: are the elements with atomic numbers above 92.
Step-by-step explanation:
Every element that lies beyond uranium in the periodic table i.e element which have atomic numbers greater than 92 are called as transuranium or transuranic elements.
All these elements are unstable and thus decay radioactively.
Only two transuranium (Neptunium and plutonium) elements are found in nature. All others are synthesized.
