Bond Types
Metallic low IE, "pool" valence electrons in a sea. can result in alloys
Ionic
Lattice Energy
- the attraction holding ions together
- calculated by 1. magnitude of charges 2. distance between charges (ionic r)
- higher LE = higher melting point, larger size, less charge
Naming Ionic Compounds
- crisscross method + simplify
- transition metals have charge exceptions (Fe, Cu, Cr, Mn, Co, Ni)
- ends in -ide unless PAI
Network Covalent very hard, high melting points, ex. silicates or diamond
