Hello I'm a little confused about the binding energy chart and its relevance to nuclei stability. 1) why is nickel-62 nucleas more stable than iron-58 and iron-56 though they have higher binding energy? 2) Why is binding energy lower in nuclei with least number of nucleons? correct me if I'm wrong, but my understanding is that the less nucleones there is the closer they'd be to the nucleus and therefore the strong nuclear force would be more dominant. So wouldn't make sense that nuclei with the least number of nucleons to be harder to split apart, and so have a higher binding energy? I guess that's not the case seeing that they have the lowest binding energy in the chart, but why?
