Question
Identification and Characterization of Unstable and Stable Nuclei
Nuclear stability can in general be predicted based on the
following considerations:
• Nuclei with 84 protons or more are unstable.
Nuclei containing a magic number of protons
and/or neutrons tend to be stable.
• Stable nuclei often contain even numbers of
protons and/or neutrons.
These factors are reflected in the given graph (Figure 1).
which shows the valley of stability as a function of number
of neutrons and protons.

"Magic" numbers
A magic number is the name given to certain numbers of protons or neutrons that have a high correlation to stability in nuclei:
magic numbers of protons: 2, 8, 20, 28, 50, 82
magic numbers of neutrons: 2, 8, 20, 28, 50, 82, 126, 184
▼
A plot of the number of neutrons versus the number of protons for all known stable nuclei, represented by reddish brown dots on the
graph, shows that these nuclei cluster together in a region known as the valley of stability. Nuclei with a ratio that is too high tend to
undergo beta decay. Nuclei with a ratio that is too low tend to undergo positron emission or electron capture.
