The activity of radioactive isotopes do not change with change in — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

Radioactive decay is a spontaneous nuclear process that is entirely unaffected by external physical conditions such as temperature, pressure, or chemical environment. However, the total activity ($A = \lambda N$) does change with the amount ($N$) of the active isotope present. Therefore, correct answer is A,B,C.
