Answer: The process is called as nuclear decay process.
Step-by-step explanation:
Nuclear reaction are defined as the reactions in which nucleus of an atom is involved.
Isotopes under decay process in order to attain stability.
Unstable isotopes known as parent isotopes undergo various decay processes to form stable isotopes known as daughter isotopes.
The various decay processes are:
- Alpha decay: In this process, alpha particle is released.
- Beta decay: In this process, beta decay is released.
- Gamma decay: In this process, gamma decay is released.
Hence, the process is called as nuclear decay process.
