Atomic Physics: Pauli Exclusion Principle and Periodic Table

This lecture covers the physics of atomic structure, focusing on the Pauli exclusion principle and the periodic table of elements. It explains the admissibility of half-integer values of angular momentum, the concept of electron spin, and the challenges in solving the n-body problem in quantum physics. The lecture also delves into the rules governing the states of electrons in multi-electron atoms, such as the Pauli exclusion principle and the aufbau principle. Additionally, it discusses the arrangement of elements in the periodic table based on electronic configurations and the chemical properties of alkali metals, halogens, and noble gases.
