Answer: The process is called as nuclear decay process.
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:
Hence, the process is called as nuclear decay process.
No because they have their complete octet. They are completely filled and don't need to bond with any other atoms. The full atoms that are happy are the noble gases.
Noble gases have electron shells with full valence. Valence electrons are the atom's outermost electrons and are typically the only electrons involved in chemical bonding.
Noble gases are elements that have completely filled their valence shells, completing their octets. Helium, Neon, Argon, Krypton, Xenon, and Radon are examples of noble gases.
Thus, the elements like He, and Xenon can not form bond with other atoms because they have completely filled orbital so, they are not loosing or gaining any electron from other atoms, that's why they are called “happy, full” elements.
