2.6 Primary Interatomic Bonds • Metallic Bonding – Found in metals and their alloys – 1 to 3 valence electrons that form a “sea of electrons” or an “electron cloud” because they are more or less free to drift through the entire metal – Nonvalence electrons and atomic nuclei form ion cores – Bonding energies range from weak to strong – Good conductor of both electricity and heat – Most metals and their alloys fail in a ductile manner + + + Ion Cores + - - + - - + Sea of Valence Electrons + + +
METALLIC BONDING • Arises from a sea of donated valence electrons (1, 2, or 3 from each atom). Adapted from Fig. 2.11, Callister 6e. • Primary bond for metals and their alloys 12
