Stable isotopes have balanced ratios and even numbers, making them less likely to decay. Examples like Carbon-12 and Carbon-14 illustrate this principle.
Stable isotopes have a balanced neutron-to-proton ratio and even numbers of protons and neutrons, making them less likely to decay. For example, Carbon-12 is stable with a 1:1 ratio, while Carbon-14 is unstable due to an imbalance with 6 protons and 8 neutrons. Nuclei with magic numbers of protons or neutrons form complete shells and are stable.
