1. Radioactivity: Radioactivity is the emission of high energy particles through the natural phenomenon of the decay of unstable isotopes of chemical elements into more stable forms, which are called daughter products. This type of emission is generally called nuclear radiation. [100%] 2023-02-04 [Radioactivity]
2. Radioactivity: The nuclei of some atoms spontaneously disintegrate from one form of isotope to another until they reach a stable form. These atoms emit particles (alpha & beta) & photons (gamma rays) which are different in charge, size, penetrating power and ionization energy. [100%] 2023-12-12
3. Radioactivity: Radioactivity is the phenomenon of emission—i.e., radiation—of electromagnetic energy and subatomic particles by the atomic nuclei of some of Earth's naturally occurring chemical elements, and all those 'artificial' chemical elements made by scientists in the laboratory ...

4. Radioactivity: The subject of radioactivity deals with phenomena exhibited by a special class of bodies of high atomic weight of which uranium, thorium, radium and actinium are the best known examples. These substances possess the property of spontaneously emitting radiations of ... [100%] 2022-09-02
5. Radioactivity: Radioactivity is the observed instability of the nuclei of some atoms. Over time, a radioactive substance will change its chemical composition: the radioactive isotopes will disappear, and decay products — usually different elements — will form.
