), indicating that nuclear forces are "saturated" in mid-sized nuclei.

The curve of binding energy is a graph that plots against the atomic mass number ( The curve of binding energy

Beyond iron, the binding energy per nucleon gradually decreases. This happens because the repulsive electrostatic force between protons begins to overcome the short-range strong nuclear force. Saturation Region: Between mass numbers , the binding energy is relatively constant (around ), indicating that nuclear forces are "saturated" in

) . It illustrates the stability of atomic nuclei and explains why certain nuclear reactions—like fusion and fission—release energy. Peak Stability: The curve peaks around a mass number of to Saturation Region: Between mass numbers , the binding

Heavy, less stable nuclei like Uranium-235 split into smaller fragments. These fragments are closer to the iron peak, meaning they have higher binding energy and release the "missing" energy during the split. Stellar Nucleosynthesis

. Nuclei in this "iron peak" (notably and Nickel-62 ) are the most tightly bound and stable in the universe.
