Which of the following nuclides would be stable?

Question

Quizplus · Accepted Answer

A nuclide is considered stable if it exists indefinitely without decaying into other isotopes or elements. Nuclides with an excessive number of protons or neutrons or a high ratio of protons to neutrons tend to be unstable. Out of the given options, ${ } _ { 83 } ^ { 209 } \mathrm { Bi }$ is the only nuclide that falls near the stability line and has a half-life of more than a billion times the age of the universe, making it relatively stable. The other nuclides have either too few or too many neutrons relative to their number of protons and are, therefore, unstable.
