Class 1 Metallic bonding: Found in metals and alloys‚ 1‚ 2‚ or 3 valence electrons that are not bound to any particular atom in the solid. They drift throughout the entire metal. This results in a sea of electrons. These free electrons result in good electrical and heat conductivity. Coordination number is 8 or 12 (number of nearest neighbors). Ionic Bonding Found in compounds that are composed of both metallic and nonmetallic elements. Metallic element gives up valence electrons to the
