WebThe electromagnetic force acts as a disruptive force in large nuclei, creating repulsions which help in fission. The electromagnetic force, although disruptive at long range, is attractive at short range and helps keep small nuclei together. The strong force is short-range, and therefore of no major importance in nuclear energy considerations. WebAs nouns the difference between fission and decay is that fission is the process whereby one item splits to become two while decay is the process or result of being gradually … WebThe Decay Chain Teacher Answer Key provides questions and answers to review with students. 7.

The emission of several neutrons in the fission process leads to the possibility of a chain reaction if at least one of the fission neutrons … WebWhat Is Nuclear Fission? When the nucleus of an atom splits into lighter nuclei through a nuclear reaction the process is termed as nuclear fission. This decay can be natural spontaneous splitting by radioactive decay, or can actually be simulated in a lab by achieving necessary conditions (bombarding with neutrinos).
