Question
A certain nucleus X has a mass number 14 and atomic number 6. The nucleus X changes to `"_7Y^14` after the loss of a particle. A radioactive substance is oxidized. What change would you expect to take place in the nature of its radioactivity? Give a reason for your answer.
Solution
No change. Since the phenomenon of radioactivity is not due to the orbital electrons which would be easily affected by such changes. Radioactivity is the property of the nucleus.
