Abstract

This chapter describes the three basic types of chemical bonds that join atoms and ions together. It discusses the properties associated with each type of bond those are metallic, ionic, and covalent. The chapter describes the weaker forces that act among molecules. It focuses on the properties of the bonds, bond energies, bond lengths, covalent, and ionic radii. The chapter illustrates the attraction between positive ions and surrounding freely mobile electrons. It discusses the geometry of molecules. The dipole moment of a polyatomic molecule is determined by both, the bond polarity and molecular geometry. The chapter provides an overview of intermolecular forces. It explains energy–distance relationship in bond formation. The most important determining factor in the geometry of covalently bonded molecules is the number of electron pairs in the valence shell of the atoms involved.
