Lecture
This lecture covers the atomic models proposed by Thomson and Rutherford, highlighting the challenges faced in interpreting atomic spectra. It explains the quantization of energy in the context of atomic spectra, the emission and absorption spectra of atoms, and the development of the Bohr model. The discussion delves into the experimental evidence that led to the rejection of Thomson's model and the introduction of Rutherford's planetary model. The lecture concludes with the limitations of the planetary model and the introduction of Niels Bohr's model, which provided a more accurate description of the hydrogen atom's structure.
