In a covalent bond, two nuclei share electrons to form a stable bond. The nuclei in a covalent bond do not lose their identity or mass. They remain intact within the bond, attracting the shared electrons to keep the bond stable.
Atoms with stable nuclei are least likely to be radioactive. Typically, atoms with an even number of protons and neutrons are more stable and less likely to undergo radioactive decay. This includes elements such as carbon-12, oxygen-16, and nitrogen-14.
A smaller nucleus is generally more stable. Below are some general rules: # (Except for really small nuclei) All stable nuclei contain a number of neutrons that is equal to or greater than the number of protons. # Nuclei with too few or too many neutrons is unstable. # If a nuclei has even numbers of nucleons, it's generally more stable. # Nuclei with "magic numbers" usually tend to be more stable.

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