CHEM 177 Naming Compounds 1 Naming Inorganic Compounds 1. metal cations having only 1 possible charge state: name = metal followed by ion Group 1A (+1), 2A (+2), Al 3+ , Zn 2+ , and Ag + 2. Metal cations having multiple possible charge states: name = metal (charge state – Roman numerals) followed by ion older nomenclature: lower charge state – suffix: -ous larger charge state – suffix: -ic 3. Cations formed from nonmetals (polyatomic cations): -ium ion Know: hydronium ion H 3 O + ammonium ion NH 4 + 4. Monoatomic anions – replace end of elemental name by -ide name = First part of element name - ide followed by ion Know: Group 7A or 17 (– 1), rows 1 – 5 Group 6A or 16 (– 2), rows 1 – 5 N 3- 5. Simple polyatomic ions: Know: OH - hydroxide CN - cyanide O 2 2- peroxide 6. Oxyanions – oxygen containing polyatomic anions Only need to know the name of the common or representative anion Know the rules. + 1 O atom per- -ate per chlor ate ClO 4 - common representative
