Formation of an Ionic Co mpound is favored by any factor that increases the Net Energy Released: (a) Low Ionization Energy (characterist ic of Metals) (b) High Electron Affinity (characterist ic of Nonmetals) (c) High Lattice Energy. The Lattice Energy depends on: Ø respective charges of ions Ø respective sizes of io ns 2. Most compounds formed between Metals and Nonmetals are Ionic Compounds Elements on the lower lefthand side of Periodic Table (Metals with low I.E.) Elements on the upper righthand side of Periodic Table (Nonmetals with high E.A.)
