Question

A radioactive disintegration differs from a chemical change in being

• A. An exothermic change
• B. A spontaneous process
• C. A nuclear process
• D. None of these

Answer 1

Answer: (C)

A nuclear process

Radioactive decay also known as nuclear decay. Radioactivity decay is a process by which a nucleus of an unstable atom loses energy by emitting ionizing radiation. A material that spontaneously emits this kind of radiation which includes the emission of alpha particles, beta particles, gamma rays and conversion electrons is considered radioactive. Chemical reaction does not involve the nuclei disintegration.
