Unformatted text preview: metal. The underlying atoms have a net positive charge due to the loss of a few electrons to the electron sea. It results in good electrical conductivity for metals and metallic lustre Ionic Bonding Found in materials that typically come a metal with a non metal. Ceramics Metal: sodium, potassium, iron all give up electrons Nonmetal:-chlorine, bromine,oxygen, nitrogen all accept electrons Covalent bonds can be weak or strong Directionality has important implications for properties. Polymers have covalent bonds and polymer chains can be very strong along the backbone of the chain...
