nuclei decay proton radioactivity radionuclide Nature is so that the same element can exist in the form of two or more variations called isotopes. Isotopes differ from each other by the number of neutrons in the nucleus and by the mass number. Isotopes can be divided into stable and unstable....
Since its discovery in 1896 by physicists Henri Becquerel, Pierre Curie, and Marie Curie, radioactivity has provided clues to the laws that govern nature. Today, the DOE Office of Science supports nuclear decay experiments to answer fundamental questions like: Why is there more matter than anti-m...
s a fire. As everything around us is naturally a little bit warm, the world is also a little bit radioactive. Cosmic raysrain down from outer space 24/7. Radon gas has bubbled out of rocks for billions of years. The heat inside the earth is about50% due to radioactive decay of ...

Radioactivity has a wide range of uses, including nuclear power, in medicine, and in dating organic and geological samples. It is also potentially dangerous, as high-energy particles and radiation can damage and kill cells, and alter DNA, causing cancer. Radioactive Decay Unstable atomic nuclei ...
Radioactive decay:Radioactive decay is a process by which an unstable nucleus loses energy by radiation. Material containing unstable nuclei is considered radioactive. Answer and Explanation: Radioactivity is defined as the act of emitting radiation spontaneously. If a nucleus is unstable it will...
