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