1. Chemical Bonding-Focus on Metallic Bonds! Bonding: Ionic, Metallic, & Covalent

2. Bonding in Metals Group of closely packed cations & free electrons. Good conductors of electricity because the electrons are free to travel through the metal. Alloys: Mixture of 2 or more elements, at least one is a metal. Often have properties better than pure metals! Ex: Sterling silver, Brass, & Stainless steel

3. “electron sea” METALLIC Bond Formation Type of Structure Solubility in Water Electrical Conductivity Other Properties Melting Point Types of Bonds Physical State e - are delocalized among metal atoms very high yes (any form) no malleable, ductile, lustrous solid
