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 (

The most common one, 210Po, has 82 protons and 128 neutrons. When 210Po decays, it emits an alpha particle, which is a helium nucleus (2 protons and 2 neutrons). 210Po decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason that authorities failed to discover toxic amounts of 210Po in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of 210Po become after it emits an alpha particle?arrow_forward
