Radioactivity is the spontaneous decay in the structure of an atom's nucleus.
Is spontaneous decay possible in the nucleus of an atom?
- The spontaneous breakdown of an atom's nucleus by the emission of particles and/or radiation is referred to as radioactivity. Radiation is the emission of energy through space as particles or waves.
- Radioactive decay is a natural process in which the nuclei of unstable isotopes emit radiation as they decay to more stable nuclei. All of the decay processes happen on their own, but the rates at which different isotopes decay vary greatly.
- Radioactive decay in which certain unstable nuclei of heavier elements split into two nearly equal fragments (nuclei of lighter elements) and release a large amount of energy.
- Radioactivity, also known as radioactive decay, is a natural process. It is because radioactive elements continuously emit radiation as a result of reactions occurring within them.
