Electronic Structure of Atoms: Polyelectronic Atoms

This lecture delves into the electronic structure of atoms, focusing on polyelectronic atoms and the repulsion between electrons. It covers the energy dependence on the principal quantum number and azimuthal quantum number, as well as the effective nuclear charge felt by electrons. The discussion extends to the Slater rules for shielding and the concept of electron configurations. The lecture also explores the properties of atoms, such as atomic radius and covalent radius, and provides insights into the periodic table's organization. Additionally, it touches on quantum numbers, the Pauli exclusion principle, and the Hund rule in determining electron configurations.
