In one average lifetime of a radioactive nucleus,
- A more than half the active nuclei decay
- B half the active nuclei decay
- C less than half the active nuclei decay
- D all the nuclei decay
Answer & Solution
Correct Answer
(A) more than half the active nuclei decay
Step-by-step Solution
Detailed explanation
The relation between half-life and the average life is, T1/2=0.693 τ Average life of radioactive sample is the amount of time required for it to get decayed by 63.2 % of its original amount. So it is more than half the nuclei decay.
