Consider two nuclei of the same radioactive nuclide. One of the nuclei was created in a supernova explosion 5 billion years ago. ihe other was created in a nuclear reactor \(5 \mathrm{~min}\) ago. The probability of decay during the next time is
- A different for each nuclei
- B nuclei created in explosion decays first
- C nuclei created in the reactor decays first
- D independent of the time of creation
Answer & Solution
Correct Answer
(D) independent of the time of creation
Step-by-step Solution
Detailed explanation
The decay's constant \((\lambda)\) and half-life period of radioactive nuclei remains constant and independent of time of creation of radioactive nuclei. Hence, the probability of decay during the next time : independent of the time of creation.
