What are radioactive elements? Give a few examples.
Explain Radioactive Elements
Elements that give off alpha particles, beta particles, and gamma particles as radiation when they disintegrate are called radioactive elements. All elements whose atomic numbers are greater than 83 are radioactive. Radioactive elements are unstable isotopes that release subatomic energy as they decay. For example, radium, thorium, uranium, radon, polonium, etc.
