" These entities were notably missing from the J.J. Thomson's "plum pudding" model and were shown to exist in an experiment in which Rutherford fired alpha particles at a piece of gold foil.
One formula approximating the mass of these objects contains an asymmetry term and is named after Bethe and Weizsacker. George Gamow proposed the liquid drop model to explain the shape of these objects. The composition of these structures relate to "magic numbers" as predicted by the shell model, though deformations must be accounted for in their (*) "island of stability." These entities were notably missing from the J.J. Thomson's "plum pudding" model and were shown to exist in an experiment in which Rutherford fired alpha particles at a piece of gold foil. For ten points, identify these structures consisting of protons and neutrons that are located at the center of an atom.
