Suppose you could watch radioactive atoms decay. It would probably get quite boring as time went by. Why? Check all that apply.

Question

Revolt · Accepted Answer

A: The initial decay rate is very fast, but the decay rate decreases over time.; B: Due to randomness, the last couple of radioactive atoms may take a long time before they become nonradioactive.; C: The pattern becomes very predictable.; D: Only a few radioactive nuclei are left to decay, so fewer and fewer atoms decay.; E: The rate of the decay decreases with each half-life cycle.
