In a radioactive decay, the number of nuclei undergoing decay per unit time is proportional to the total number of nuclei in the sample. Which of the following describes it best?
Answer & explanation
Correct answer: option 1
In a radioactive decay, the number of nuclei undergoing decay per unit time is proportional to the total number of nuclei in the sample. This is given by :
\(\Delta \) N / \(\Delta \) T ∝ N
Or $ \frac{\Delta N}{N} \propto \Delta T$
