The answer to the second question is no. No one can tell when a particular atom of a radioactive substance will decay. However, when we are dealing with large numbers of radioactive atoms we can predict how long it will take for a certain number or percentage of the atoms to decay. For each radioactive isotope, we can predict a certain half-life.
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.
