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.
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.
Helium is the most stable element. All noble gases are "stable", but helium has the least amount of electrons, this causes it to be less affected by London dispersion forces (Vanderwal). This is why helium has the lowest boiling point of all elements.

That refers to atomic nuclei being stable - not disintegrating, or at least not disintegrating very quickly.
1 proton, 3 neutrons
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.
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.
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.
