▶Define RADIOACTIVITY_
Answers
Explanation:
Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability. Because the nucleus experiences the intense conflict between the two strongest forces in nature, it should not be surprising that there are many nuclear isotopes which are unstable and emit some kind of radiation.
pls mark it as brain list
the property possessed by some elements (such as uranium) or isotopes (such as carbon 14) of spontaneously emitting energetic particles (such as electrons or alpha particles) by the disintegration of their atomic nuclei also : the rays emitted.
eg :
Some examples include hydrogen-3, carbon-14, potassium-40, and tellurium-123. Radioactive isotopes can also be made artificially. The usual process is to bombard a stable nucleus with protons, neutrons, alpha particles, or other subatomic particles.
