The characteristics of the elements in nature according to the liquid drop model can be estimated based on the Bethe-Weizsäcker empirical equation for the binding energy of each nucleon given by: Z(Z-1) (A – 22) Ebe/nucl = QvolA - AsurfA3 – Acoul a asym + [+0] A A3/4 2 apair 1 A3 - Where A is the mass number, Z the number of protons, avol = = 14 MeV, asurf 13 MeV, acoul = 0.60 MeV, Aasym = 19 MeV and a pair = 34 MeV. The curve for the binding energy equation per nucleon is given in the figure below. -8.8 MeV 7 A A=56 Based on the curve: Explain and give an argument why atomic nucleus, generally light or heavy, tend to be unstable? And why is it stable?
