The Nucleus and Its Applications
The discoveries of radioactivity and isotopes were extraordinary advances. And as usual, they also raised new questions about the structure of atoms, questions that involved the atomic nucleus. We saw in Chapter 17 that the transformation rules of radioactivity could be understood in terms of the Rutherford-Bohr model of the atom. But that model said nothing about the nucleus other than that it is small, has charge and mass, and may emit an a or a β particle. This implies that the nucleus has a structure that changes when a radioactive process occurs. The question arose: Can a theory or model of the atomic nucleus be developed that will explain the facts of radioactivity and the existence of isotopes?
