What is the name of the ionic compound Ga2O3, K2(CrO4), ZnBr2, Ag(ClO3), Na3N, Rb(NO3), Ca(NO2)2, Cs2(SO3), SrO, Mg(C2H3O2)2?
Understand the Problem
The question requires providing the names of the following ionic compounds: Ga2O3, K2(CrO4), ZnBr2, Ag(ClO3), Na3N, Rb(NO3), Ca(NO2)2, Cs2(SO3), SrO, Mg(C2H3O2)2. For each, we need to apply the rules of ionic nomenclature, which involve identifying the ions present and using appropriate prefixes or suffixes where necessary, especially for transition metals or polyatomic ions.
Answer
The names of the ionic compounds are: Gallium oxide, Potassium chromate, Zinc bromide, Silver chlorate, Sodium nitride, Rubidium nitrate, Calcium nitrite, Cesium sulfite, Strontium oxide, and Magnesium acetate.
Here are the names of the ionic compounds: Ga2O3: Gallium oxide K2(CrO4): Potassium chromate ZnBr2: Zinc bromide Ag(ClO3): Silver chlorate Na3N: Sodium nitride Rb(NO3): Rubidium nitrate Ca(NO2)2: Calcium nitrite Cs2(SO3): Cesium sulfite SrO: Strontium oxide Mg(C2H3O2)2: Magnesium acetate

More Information
When naming ionic compounds, the cation (positive ion) is named first, followed by the anion (negative ion). For simple binary ionic compounds, the name of the anion is modified to end in '-ide'. Polyatomic ions have specific names that must be memorized. Transition metals require the use of Roman numerals to indicate their charge, except for those that only form one charge (like zinc and silver).
Tips
A common mistake is not recognizing polyatomic ions and incorrectly naming them. Another mistake is forgetting to use Roman numerals for transition metals that can have multiple charges.
