Here are the essential concepts you must grasp in order to answer the question correctly.
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. Typically, the cation is named first, followed by the anion. For transition metals, the oxidation state is indicated using Roman numerals, which is crucial for accurately naming compounds like Fe(NO3)2, where iron can have multiple oxidation states.

Polyatomic Ions
Polyatomic ions are ions composed of two or more atoms covalently bonded together, which carry a net charge. Common examples include nitrate (NO3-) and sulfate (SO4^2-). Recognizing these ions is vital for correctly naming compounds that contain them, as they often appear in ionic compounds and influence the overall charge balance.
