Answer 2

Answer:

Radioactive elements are made up of atoms whose nuclei are unstable and give off atomic radiation as part of a process of attaining stability. The emission of radiation transforms radioactive atoms into another chemical element, which may be stable or may be radioactive such that it undergoes further decay.

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.
