    Explanation:<\/strong><\/h3>\n\n\n\n

    In inorganic chemistry, the naming and writing of chemical formulas follow systematic rules set by IUPAC. These rules depend on whether a compound is ionic, molecular, or acidic.<\/p>\n\n\n\n

    Ionic compounds<\/strong> consist of a metal and a nonmetal. The cation (metal) is written first, followed by the anion. Transition metals may have multiple oxidation states; their charges are indicated with Roman numerals (e.g., Sn(IV) = Sn\u2074\u207a). Polyatomic ions, like nitrate (NO\u2083\u207b) or phosphate (PO\u2084\u00b3\u207b), retain their names and are combined with cations based on charge balance. For example, tin(IV) nitrate becomes Sn(NO\u2083)\u2084 because Sn\u2074\u207a requires four NO\u2083\u207b ions to balance the charge.<\/p>\n\n\n\n

    Molecular compounds<\/strong>, formed between nonmetals, use Greek prefixes (mono-, di-, tri-, etc.) to indicate the number of atoms. For instance, dinitrogen tetrasulfide (N\u2082S\u2084) directly reflects the number of atoms.<\/p>\n\n\n\n

    Acids<\/strong> are named based on the anion they contain. Binary acids (hydrogen + one other element) use the prefix \u201chydro-\u201d and the suffix \u201c-ic\u201d (e.g., HBr = hydrobromic acid). Oxyacids, which contain hydrogen, oxygen, and another element (typically a nonmetal), are named from their polyatomic ions. If the ion ends in:<\/p>\n\n\n\n

      \n
    • -ate<\/strong> \u2192 acid ends in -ic<\/strong> (e.g., HBrO\u2083 = bromic acid)<\/li>\n\n\n\n
    • -ite<\/strong> \u2192 acid ends in -ous<\/strong> (e.g., HBrO\u2082 = bromous acid)<\/li>\n\n\n\n
    • per-…-ate<\/strong> \u2192 acid is per-…-ic<\/strong> (e.g., HBrO\u2084 = perbromic acid)<\/li>\n\n\n\n
    • hypo-…-ite<\/strong> \u2192 acid is hypo-…-ous<\/strong> (e.g., HBrO = hypobromous acid)<\/li>\n<\/ul>\n\n\n\n

      Understanding oxidation states and ion charges is crucial for writing correct formulas.<\/p>\n\n\n\n
