Question

From a large sample of the isotope

The half-life can be estimated from a large sample because it averages out the random nature of decay.

Misunderstanding Half-Life Calculation

Students often confuse the half-life with the total decay time, thinking it represents the entire duration for a sample to decay completely.

Emphasize that half-life is the time taken for half of the radioactive nuclei to decay, not the time for the entire sample to decay.
