NAMING COMPOUNDS WITH TRANSITION METALS

Aim: To name compounds with multiple oxidation state metals using roman numerals.

Jan 23­12:44 PM 1 Naming Transition Metal Compounds 2015 Filled In.notebook January 08, 2016

Iron Oxide Iron Oxide Fe+2 O­2 Fe+3 O­2 Fe+3 O­2 O­2 FeO Fe2O3 Iron (II) Oxide Iron (III) Oxide

Which formula is correct? BOTH. The name needs a roman numeral with the metal in order to determine which cation is present.

Compounds containing metals with multiple oxidation states must have a roman numeral to indicate which cation is present.

Naming Compounds with Multiple oxidation state metals

1. List all parent ions present. AuCl3 Determine the charge and quantity Au+3 Cl­ of the anion FIRST. Cl­ Cl­ 2. Use the anion charges and the (+3) (­3) neutrality rule to determine which metal cation is present. Au must have a +3 charge to make the 3. Name the compound and include compound neutral. a roman numeral representing the charge number of the metal Gold (III) Chloride cation.
