Chemical Bonding: Crystal Lattices and Ionic Solids

This lecture covers the fundamentals of chemical bonding, focusing on crystal lattices and ionic solids. It explains the concept of elementary cells in crystal lattices, the 14 Bravais networks, and the types of elementary meshes. The lecture delves into the structures of ionic solids, discussing the arrangements of anions and cations, as well as the different sites cations can occupy. It also explores the properties of ionic compounds, such as high melting points and solubility in water. Additionally, the lecture introduces molecular orbitals and the formation of covalent bonds through orbital overlap. Lewis structures and the distribution of electrons in molecules are also discussed.
