The process of natural decay of some heavy nuclides is because of the phenomenon:
Correct answer: D. Radioactivity
- A. Emission Spectra
- B. Nuclear fusion
- C. Nuclear fission
- D. Radioactivity
Explanation
Radioactivity is the spontaneous emission of radiation in the form of particles or high-energy photons resulting from a nuclear reaction. It is also known as radioactive decay, nuclear decay, nuclear disintegration, or radioactive disintegration. Alpha, beta, and gamma decay are three common radioactivity processes

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.

In free states, the mass of the nucleus is always:
The detection and estimation of an element in a mixture is sometimes nearly impossible, if it is present in very minute traces or if it's chemical properties are very similar to those of other elements in the mixture. An effective technique is developed for these purposes is known as?
During radioactive decay of a nucleus zXA, β emission takes place along with the daughter nucleus. Because of this beta particle emission, the mass number (A) of the parent nucleus:
