4. Which of the following statements concerning transuranium elements is incorrect? a) Atomic number > 92 b) Example is Thorium c) Decay radioactively as they are unstable d) Elements after Uranium
Answer: b Explanation: Transuranium elements are those that come after Uranium (Z = 92), are unstable, and decay radioactively into other elements. However, because Thorium has an atomic number of 90, it is not a transuranium element.
