In that description, the VSEPR model uses rules for predicting structures that are based on observations of the geometries of many molecules. (b) Mg and F will form an ionic compound; Mg is a metal while F is a nonmetal. Basic Concepts of Chemical Bonding Chemical Bonds forces of attraction which hold atoms or ions together 3 fundamental types of bonding Ionic - metals & nonmetals Covalent - nonmetals (semimetals) Metallic - metals 1. CHAPTER 9: CHEMICAL BONDING I: BASIC CONCEPTS 241 9.19 (a) I and Cl should form a molecular compound; both elements are nonmetals. Chapter 8. The ions are packed as closely as possible. Chapter 8 – Basic Concepts of Chemical Bonding Section 8.1 – Chemical Bonds, Lewis Symbols, and the Octet Rule Whenever two atoms or ions are strongly attached to each other, we say there is a chemical bond between them. One more will give it a complete octet. %PDF-1.4 The bond with the highest bond order is both the shortest and the strongest.
