These notes cover the fundamental concepts needed to understand atomic structure, starting from early discoveries to modern quantum theory. It begins with the discovery of subatomic particles—electrons, protons, and neutrons—and how scientists like Thomson, Rutherford, and Bohr contributed to atomic models. You’ll find a clear explanation of Rutherford’s nuclear model and why it failed, followed by Bohr’s model, including energy levels, quantization, and its application to hydrogen ...
