Binding Energy per Nuclueon

The liquid drop model is a simple, yet commonly used method for calculating the mass of a nucleus. I liked what the figure on the wikipedia page of

When compared to the published values the liquid drop model didn't do that badly - the largest errors came from the low Z elements which have more accurate QM models (that can be "easily" solved) and the high Z elements which are crazy little beast.

It is kinda interesting to know how complex the periodic table is, and how little I know about it. I didn't know what Z Scandium was (sorry trivia team).  So many little quirks that there isn't theory for.
