Metalic bonding

  1. 1. Metallic Bonding
  2. 2. Metallic Bonding Metallic bonding is the attraction between positive ions and surrounding freely mobile electrons. Most metals contribute more than one mobile electron per atom. “electron sea” e1- e1- e1- e1- e1- e1- e1- e1- e1- e1- e1- e1- e1- e1- e1- e1- Free electrons + + + + + ++ + + + + + + + Cations Bailar, Jr, Moeller, Kleinberg, Guss, Castellion, Metz, Chemistry, 1984, page 245
