Chemical Bonds: Types and Properties

This lecture introduces the science of materials, focusing on chemical bonds in mechanical engineering. It covers different types of atomic and molecular bonds, their characteristics, and effects on material properties. The lecture discusses the potential energy of Lennard-Jones, interatomic forces, and the role of valence electrons in forming ionic, covalent, metallic, and intermolecular bonds. It also explores the concept of electronegativity and the relationship between bond energy and enthalpy. The session concludes with a discussion on the conductibility of ionic compounds and the formation of covalent bonds through electron sharing.
