Analyze the Rate of Radioactive Decay
Tom [10]

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.
