Наука краще запам’ятовується, коли визначення пов’язане з тим, що можна виміряти або спостерігати.

3

After three half-lives, an ideal radioactive population has one eighth of its initial undecayed nuclei remaining.

A half-life does not mean every nucleus survives exactly that long; it is a statistical property of a population.

Конкретна перевірка

Isotopes share a proton number but differ in neutron number. Some are unstable, and their populations follow statistical decay laws described by half-life.
