Mastering Ionic Compound Naming Techniques

The video tutorial explains how to name ionic compounds by first naming the cation, usually a metal, followed by the anion, typically a nonmetal or polyatomic ion. For binary ionic compounds, the anion ends with the suffix 'ide'. Metals that form more than one type of cation require a roman numeral to indicate the charge. Examples include NaBr (sodium bromide), K2O (potassium oxide), and CaF2 (calcium fluoride). The tutorial also covers naming compounds with polyatomic ions, such as Al2(SO4)3 (aluminum sulfate) and FePO4 (iron(III) phosphate), emphasizing the importance of determining the charge to ensure the compound is charge neutral.

What is the correct order for naming ionic compounds?

• Metal first, then nonmetal

• Nonmetal first, then metal

• Cation first, then anion

• Anion first, then cation

Which suffix is typically used for the anion in binary ionic compounds?

• ate

• ide

• ous

• ite

When is a Roman numeral used in naming ionic compounds?

• When the anion is a nonmetal

• When the metal forms more than one type of cation

• When the metal forms only one type of cation

• When the compound contains a polyatomic ion
