C. Fission: may create radioactive nuclei, may undergo a chain reaction Fusion: energy source for stars Fission and fusion: large amount of energy produced
Answer by Quirkyquantummechanic. Confidence votes 77.7K. Radioactive decay is a natural process that occurs because a given atomic nucleus is unstable. The instability in the nucleus will eventually result in some kind of nuclear change (depending on the atom), and we call this radioactive or nuclear decay.Different radionuclides undergo different types of decay that include spontaneous fission, alpha decay and beta decay.adioactive decay is the spontaneous change or disintegration of an unstable atomic nucleus as it transforms itself to lose energy. It does this by the release of either parti â¦ culate radiation or electromagnetic radiation, or both.
