What are radioactive examples?
For example, uranium and thorium are two radioactive elements found naturally in the Earth’s crust. Over billions of years, these two elements slowly change form and produce decay products such as radium and radon. During this process, energy is released. One form of this energy is alpha radiation.
Which noble gases are radioactive?
radon (Rn), chemical element, a heavy radioactive gas of Group 18 (noble gases) of the periodic table, generated by the radioactive decay of radium. (Radon was originally called radium emanation.)
