The process of natural decay of some heavy nuclides is because of the phenomenon.
Correct answer: A. Radioactivity
- A. Radioactivity
- B. Fission
- C. Fusion
- D. None of the above
Explanation
This is the correct answer. Radioactivity is the spontaneous emission of radiation from the nucleus of an unstable atom. This process is known as nuclear decay. Some heavy nuclides are unstable due to having an excess of neutrons or protons, and they undergo radioactive decay to achieve a more stable configuration.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
