Consider a radioactive material of half-life `1.0` minute. If one of the nuclei decays now, the next one will decay

A

after 1 minute

B

after `(1)/(log e_(2))` minute

C

after `(1)/(N)` minute , where N is the number of nuclei present at that moment

D

after any time

Text Solution

Verified by Experts

The correct Answer is:
D

Because radioactivity is a spontaneous pheonomenon.
