1 Metals with Variable Charge Most transition metals (3-12) and Group 4A (14) metals form 2 or more positive ions, except Zn 2+, Ag +, and Cd 2+, which form only one ion Pearson Education, Inc. Chapter 5, Section 1 1

2 Metals with Variable Charge The names of transition metals with two or more positive ions (cations) use a Roman numeral after the name of the metal to identify the ion charge.

3 Naming Ionic Compounds with Variable Charge Metals

4 Naming FeCl 2 Step 1 Determine the charge of the cation from the anion. Analyze the Problem.

5 Naming FeCl 2 Step 2 Name the cation by its element name and use a Roman numeral in parentheses for the charge. Fe 2+ = iron(ii) Step 3 Name the anion by using the first syllable of its element name followed by ide. Cl = chloride Step 4 Write the name for the cation first and the name for the anion second. iron(ii) chloride
