Electronic Configuration and Periodic Table

This lecture covers the electronic configuration of atoms, including the exceptions to the Aufbau principle, the periodic table, and the periodic trends such as atomic radius. It also discusses the filling of atomic orbitals, the concept of valence electrons, and the significance of the atomic number. The instructor explains the rules for writing electron configurations and provides examples for better understanding. Additionally, the lecture delves into the concept of isotopes, the structure of the periodic table, and the historical development of atomic theory.
