Introduction to Chemical Bonding. Objectives:. Define . chemical bond.. Explain why most atoms form chemical bonds.. Describe ionic and covalent bonding.. Explain why most chemical bonding is neither purely covalent nor purely ionic.. . Ionic (Atomic) Radii & Coordination Number (CN). Ionic radius: . Hypothetical radius (size) of an ion (. cation. or anion). Calculated values from the bonding distances. CN. Number of one kind of the bond forming ions (atoms) surrounding the other, which are forming the first direct bonding. IB Topics 4 & 14. Text:. Ch 8 (all except sections 4,5 & 8). Ch 9.1 & 9.5.

Chemical formula – indicates relative # of atoms of each kind in a chemical compound by using atomic symbols & subscripts. Ionic bonds form a . giant lattice structure. Sodium chloride is an ionic compound formed by the reaction between the metal sodium and the non-metal chlorine.. During the reaction, one electron is transferred from each sodium atom to each chlorine atom.. The Covalent Bond. Section 9.1. Worldwide, scientists are studying ways to increase food supplies, reduce pollution, and prevent disease. Understanding the chemistry of compounds that make up fertilizers, pollutants, and materials that carry genetic information is essential in developing new technologies in these areas. An understanding of the chemistry of compounds requires an understanding of their bonding..
