Concept Introduction:
A unstable nucleus has more energy than that of a stable nucleus. An atom possess an unstable nucleus can be identified by the emission of radiation that the unstable nucleus does. The emission of radiation from an unstable nucleus is not induced. It is a spontaneous one.
Nuclear stability depends upon the number of nucleons present in it. There is a direct correlation between these two. The nuclei with 84 or more protons are unstable. This means the nuclei that contains 83 or less protons is stable. The nucleus that contains 83 protons is Bismuth. Bismuth (
