Quizplus · Accepted Answer

The naturally radioactive element in group 6A is Polonium (Po), which has an atomic number of 84. It is a highly toxic metal that emits alpha particles and is used in some nuclear applications such as static eliminators and sources of neutrons. The rest of the elements in group 6A (Sulfur-S, Selenium-Se, Tellurium-Te) and the lanthanide Dysprosium (Dy) are not naturally radioactive. Uranium (U), on the other hand, is a radioactive element, but it belongs to group 3B of the periodic table.
