Question 3(v)

How is the radioactivity of a radio isotope affected if it undergoes a chemical change? Give a reason for your answer.

The radioactivity of a radioactive isotope is not affected by chemical changes. This is because radioactivity is a nuclear phenomenon specifically related to the stability of the isotope's nucleus, while chemical changes involve the rearrangement of electrons and the formation or breaking of chemical bonds.
