Chemical Bonds: Types and Representation

This lecture covers the concepts of chemical bonds, including ionic, covalent, and metallic bonds, as well as the factors influencing bond formation such as electronegativity. It explains the formation of bonds through the sharing or transfer of electrons, the role of valence electrons, and the principles of Lewis theory. The lecture also discusses the representation of molecules in 2D and 3D using Lewis structures and VSEPR theory, emphasizing the importance of electron configuration and bond geometry. Additionally, it explores the properties of ionic compounds, their electrical conductivity, and the distinction between polar and nonpolar bonds.
