The Curve Of Binding Energy [DIRECT]

Light nuclei move "up" the curve to become more stable by fusing together. This process powers stars like our Sun.

), indicating that nuclear forces are "saturated" in mid-sized nuclei. The curve of binding energy

. Nuclei in this "iron peak" (notably and Nickel-62 ) are the most tightly bound and stable in the universe. Light nuclei move "up" the curve to become

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

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

) . 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
