Interpretation Introduction

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 chemical reactions because the electrons do not take part in reaction while the particles inside the nucleus does.  Isotope and nuclide are almost similar terms.  Isotopes refer to the same element that have different mass number while nuclide refer to atoms of same or different elements with specific atomic number and mass number.

Unstable nuclei emits radiation to become stable.  The process of this radiation emission is known as radioactivity.
