The Curve Of Binding Energy (Editor's Choice)

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

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 The curve of binding energy

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 The curve of binding energy is a graph

Light nuclei move "up" the curve to become more stable by fusing together. This process powers stars like our Sun. These fragments are closer to the iron peak,

) . 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

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

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