Answer:
The correct options are: a. the number of additional neutrons of an isotope is too large; d. the number of additional neutrons of an isotope is too small
Explanation:
The chemical elements that have the same number of protons in the nucleus but different number of neutrons are known as isotopes. Isotopes can be stable or unstable.
The isotope having an unstable nucleus, due to the presence of additional neutrons in the nucleus of the atom, is known as a radioisotope.
Also, chemical elements that have atomic number greater than 83 have unstable nuclei and thus they are called radioisotopes.
