The stability of a nucleus in an atom how firmly the particles are held together. Protons in a nucleus would repel each other, but with the help of neutrons, most of the mass of an atom is strongly kept in place.
In this analogy, the heads of the pennies could represent stable nuclei, while the tails could represent radioactive nuclei. Stable nuclei do not undergo spontaneous decay, while radioactive nuclei have the potential to decay and emit radiation over time.
Nuclei that have an excess of neutrons can become stable by emitting beta particles (electrons or positrons). This process helps the nucleus increase its neutron-to-proton ratio and achieve a more stable configuration.
1 proton, 3 neutrons
The stable nuclei that are not radioactive include, for example, carbon-12, oxygen-16, and neon-20. These nuclei have a balanced composition of protons and neutrons that do not undergo radioactive decay.
unstable and eventually transform into a stable form. This process is known as radioactive decay and can result in the mineral changing its chemical composition or structure.
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance. Unstable nuclei undergo radioactive decay to become more stable.
Stable nuclei have a balanced number of protons and neutrons, while unstable nuclei have an imbalance, leading to radioactive decay.
Radioactive isotopes are not stable.
Of course they are more stable, therefore they formed naturally.

The nuclei of a stable radioactive isotope will after been bombarded with a neutron produce a radiation and enormous energy and such reaction will come to an end, while the nuclei of an unstable nuclei will continue to react with little fragment of the neutron continuously (long chain nuclear reaction) until it has attain it stable phase.mind you this reaction with the little fragment of this neutron can last over 10 years.
