Lecture
This lecture covers the electronic configuration of elements, exceptions to the aufbau rule, and the structure of the periodic table. It explains how half or fully filled d orbitals affect stability, the energy levels of orbitals, and the analytical solutions for atoms. The instructor discusses the historical perspective of atomic models, the modern rules of construction based on electronic configuration, and the descriptive properties of elements. Additionally, the lecture delves into the atomic theory of John Dalton, the discovery of the atomic number, isotopes, and the classification of elements in the periodic table.
