Radioactivity | Chemical Change |
(i) It is a nuclear phenomenon and a new element is formed. | (i) I this case electronic arrangement of the combining elements change and new compounds are formed. |
(ii) It is not influenced by external condition such as temperature pressure,catalyst,light etc | (ii) Chemical change is always influence by external condition. |
(iii) It is irreversible. (iv) Energy associated is much high . | (iii) It may be reversible or irreversible. (iv) Energy associated is relatively very small.Distinction between chemical change and radioactivity. |
