Question

(c) Which part of the atom undergoes a change in the process of radioactive decay ?
(d) A radioactive substance is oxidised. Will there be any change in the nature of
its radioactivity ?
Give reason for your answer above...​

Answer 1

Answer:

c)When a radioactive atom undergoes a nuclear decay event (the significant decay modes are alpha decay, beta decay, electron capture, and spontaneous fission), the decaying nucleus undergoes a transformation in identity associated with the change in the number of protons in the nucleus.

d)A radioactive substance is oxidized. ... There will not be any change in the nature of a radioactivity of the substance because oxidation is a chemical process and does not involve the nucleus of the substance.
