In this video we'll write the correct name for BaI2. To write the name for BaI2 we’ll use the Periodic Table and follow some simple rules. • ----Essential Information for Naming Simple Ionic Compounds ---- • Metal + Non-Metal = Ionic Compound • (for example, CaCl2, KBr, or Al3N2) • ----Steps to Name Binary Simple Ionic Compounds---- • 1) Name the metal (the cation) as it appears on the Periodic Table, for example: • • Na+ = Sodium • • Mg2+ = Magnesium • • Al3+ = Aluminum • 2) For the non-metal (the anion) write the name on the Periodic Table and then replace the ending with ide. For example: • • CaCl2 = Calcium chlorine = Calcium chloride • • AlN = Aluminum nitrogen = Aluminum nitride • • Na2O = Sodium oxygen = Sodium oxide • For ionic compounds like Barium iodide, you should check to make sure the charges balance to make sure you have the right name. • Naming Resources: • • Simple Ionic Compounds: • Naming Simple Ionic Compounds • • Compounds with Polyatomic ions: • How to Name Ionic Compounds with Poly... • • Compounds with Transition Metals: • How to Name Ionic Compounds with Tran... • • Molecular Compounds: • Naming and Formula Writing for Molecu... • • Naming Acids: • How to Name Acids: Examples and Practice • For a complete tutorial on naming and formula writing for compounds, like Barium iodide and more, visit: • http://www.breslyn.org/chemistry/naming • • Drawing/writing done in InkScape (http://www.InkScape.org).
