Answer:
1. The initial decay rate is very fast, but the decay rate decreases over time.
2. Due to randomness, the last couple of radioactive atoms may take a long time before they become nonradioactive.
3. The pattern becomes very predictable.
4. Only a few radioactive nuclei are left to decay, so fewer and fewer atoms decay.
5. The rate of the decay decreases with each half-life cycle.
hope it helps!
