Answer
Half-life
Explanation
Half-life is the specific term used to describe the time required for half of the radioactive nuclei in a sample to decay.
Common mistake
Misunderstanding Half-Life Definition
Students often confuse half-life with the time taken for the entire sample to decay, rather than the time for half of the radioactive nuclei to decay.
Emphasize that half-life specifically refers to the time it takes for half of the radioactive nuclei in a sample to decay, not the entire sample.
