    How half-life is related to the random nature of radioactive decay.
    Heavy elements spontaneously decay by breaking apart to form new elements. The radioactive decay of any given isolated atom is impossible to predict.

    Nevertheless, amongst large quantities of the same atom, there will still be atoms that decay in a consistent manner. It is still impossible to predict when an individual atom will decay and therefore deemed random. Over time all of the atoms will decay.

    Half-life is the time period required for half of the atoms in a given quantity to spontaneously decay.
