Lecture
This lecture delves into the principles of quantum physics governing the electronic configuration of atoms, focusing on the rules of exclusion, Hund, and Aufbau. It explores the formation of molecular bonds, including covalent and ionic bonds, and the van der Waals interactions. The instructor explains the concepts of effective potential, electron affinity, and the mechanisms behind keesome, debye, and London interactions. The lecture also covers hydrogen bonding and its significance in DNA structure and protein folding. By the end, students will have a comprehensive understanding of the energy scales and strengths of various molecular bonds.
