Mokslas geriau įsimena, kai apibrėžimas susiejamas su tuo, ką galima išmatuoti ar stebėti.
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.
Konkretus patikrinimas
Isotopes share a proton number but differ in neutron number. Some are unstable, and their populations follow statistical decay laws described by half-life.
