The nuclear stability curve depicts the binding energy per nucleon as a function of the mass number (A) of atomic nuclei. The curve shows that nuclei with intermediate mass numbers, around A = 56 for iron, have the highest binding energy per nucleon, indicating the greatest stability.
The N-Z Graph. A graph of the number of protons (Z) against the number of neutrons (N) can be used to predict which isotopes are stable and which will emit alpha or beta radiation. Below is a N – Z graph: The bold black line running through the graph represents the stability line. Isotopes that fall along this line are usually stable.
Definition. Nuclear stability refers to the ability of an atomic nucleus to maintain its structure without undergoing radioactive decay. A stable nucleus is characterized by a balanced ratio of protons and neutrons, which allows it to remain intact over time.
This nuclear stability curve shows the line of stable isotopes and which unstable isotopes will emit alpha or beta particles
