Concept Map

The chapter's concept map ties every topic together under the single title "Atomic and Nuclear Physics," branching into two broad halves that mirror the unit's two main themes. The "Atom models" branch further splits into the alpha-scattering experiment, the J.J. Thomson model, the Rutherford model, and the Bohr atom model - tracing the historical progression by which the atom's structure was worked out. The "Nucleus" branch further splits into the hydrogen spectrum (linking back to the Bohr model's central success), the general properties of the nucleus, binding energy, radioactive decays, nuclear fusion and fission, and elementary particles. Read as a whole, the map is a compact visual reminder that this entire chapter is organised around exactly two connected questions: what does the atom look like on the inside (resolved through the sequence of atom models) …
