Webneutrons is enough to provide stability, hence N ≈Z for small Z. As the number of protons gets larger, an excess of neutrons is needed to overcome the proton-proton repulsion. The stability of nuclei follows a definite pattern. The majority of stable nuclei have both even Z and even N ("even-even" nuclides). WebKey Features of the Graph. At low values of A: Nuclei tend to have a lower binding energy per nucleon, hence, they are generally less stable; This means the lightest elements have weaker electrostatic forces and are the most likely to undergo fusion; Helium (4 He), carbon (12 C) and oxygen (16 O) do not fit the trend Helium-4 is a particularly stable nucleus …
