What aspect of nuclear fission makes it possible for a chain reaction to occur? What is the difference between a chain reaction in a bomb and one in a nuclear power plant?
One-half of the nuclei of a given radioisotope decays during one half-life. Why doesn't the remaining half decay during the next halflife?
