In a couple of minutes, almost all atoms of element A will have decayed after repeated halving of the initial number of atoms, but very few of the atoms of element B will have done so as only a tiny fraction of its half-life has elapsed.

The accompanying table shows the reduction of a quantity as a function of the number of half-lives elapsed.
