Definition of stable isotopes

WebRadioactive isotopes are isotopes that undergo spontaneous nuclear decay in other to become a stable isotope (and get closer to the belt of stability). During nuclear decay, radiation is emitted by the emission of nuclear particles. There are different types of nuclear decay that an isotope might experience. WebStable isotopes remain unchanged indefinitely, but "unstable" (radioactive) isotopes undergo spontaneous disintegration. An "isotopically labeled compound" has one or more of its atoms enriched in an isotope. ... As chemists used the criterion of chemical indistinguishability as part of the definition of an element, they were forced to conclude ...
