Question

“Radioactivity is a nuclear phenomenom” comment ?​

Answer 1

Answer:

Any physical change (such as change in pressure and temperature) or chemical change (such as excessive heating, freezing, action of strong electric and magnetic fields, chemical treatment, oxidation etc.) does not change the rate of decay and the nature of radiation emitted by the substance. This shows clearly that the phenomenon of radioactivity cannot be due to the orbital electrons which could easily be affected by such changes. Therefore the radioactivity should be the property of the nucleus. Thus the radioactivity is a nuclear phenomenon.

Answer 2

Hi mate!!

Any physical or a chemical change does not alter the rate of decay of a radioactive substance. So, it is clear that the phenomenon of radioactivity cannot be due to orbital electrons. Thus, radioactivity should be a nuclear phenomenon. It is the process of spontaneous emission of alpha, beta or gamma radiations from the nuclei of an atom.
