Name the following ionic compounds: (j) Ag₂Cr₂O₇.

Verified step by step guidance

1. Step 1: Identify the cation and the anion in the compound. In Ag2Cr2O7, Ag is the cation and Cr2O7 is the anion.
2. Step 2: Name the cation first. The cation Ag is silver.
3. Step 3: Name the anion. The anion Cr2O7 is dichromate.
4. Step 4: Combine the names of the cation and anion. In this case, the name of the compound is Silver Dichromate.

Key Concepts

Ionic Compounds

Ionic compounds are formed when atoms transfer electrons, resulting in the formation of positively charged cations and negatively charged anions. These oppositely charged ions attract each other, creating a stable compound. Understanding the nature of ionic bonds is essential for naming and writing formulas for these compounds.

Nomenclature of Ionic Compounds

The nomenclature of ionic compounds involves specific rules for naming the cations and anions. Cations, typically metal ions, retain their elemental name, while anions often have their names modified, usually by adding an '-ide' suffix or using a specific name for polyatomic ions. Familiarity with these naming conventions is crucial for accurately identifying compounds.

Polyatomic Ions

Polyatomic ions are ions composed of two or more atoms that are covalently bonded and carry a net charge. Common examples include sulfate (SO4^2-) and chromate (CrO4^2-). Recognizing polyatomic ions and their charges is vital for correctly naming compounds that contain them, such as Ag2Cr2O7, which includes the dichromate ion (Cr2O7^2-).
