Atomic Structure: Fundamentals

This lecture covers the basics of atomic structure, starting from the concept of indivisible particles proposed by ancient philosophers to the modern understanding of protons, neutrons, and electrons forming the nucleus. It explains the atomic hypothesis, the Bohr model, quantum mechanics, and the wave-particle duality of light. The lecture also delves into the electromagnetic nature of light, the photoelectric effect, and the emission of photons by excited hydrogen atoms.
