An appropriate model of the radioactive decay of a group of atoms would be popping a bag of popcorn. This analogy works because, similar to radioactive decay, the popping of the popcorn kernels is unpredictable in terms of when each kernel will pop, and once a kernel has popped (an atom has decayed), it cannot revert to its original state.
