Concept explainers
Interpretation:
Radioactive nuclide is a term that is used to designate an atom with what type of nucleus has to be chosen from the given options.
Concept Introduction:
If the reaction occurs in the nucleus of an atom then it is known as nuclear reaction. These reactions are not considered as ordinary
Unstable nuclei emits radiation to become stable. The process of this radiation emission is known as radioactivity.
