... energy to decrease as more neutrons are added and has its greatest effect for high mass numbers. The fourth term accounts for the fact that at low masses (Z < ~20), there is a tendency for the number of protons and neutrons to be symmetric, e.g. A = 2Z. The (A2Z)2 proportionality is to account for t ...
