Question

D. Naming Binary lonic Compounds Fixed metals in group IA, IIA or III B and most of III A along with Zn, & Ag: These cations are named with just the element name and anion is named by taking the root of the element name and finishing with-ide. Non fixed metals in all other groups: The cation is named with its oxidation number or charge in parenthesis and then the anion is named by taking the root of the element and adding-ide. 1. Complete the following table. Name of non- metal anion Name of Metal Compound cation Name of compound (first element) (second element) N Sodium ion Na MnF2 Manganese(II),Mn2 Fluoride ion, F Manganese (II) fluoride BaC2 Oxide ion 02 Sodium oxide HgCl2 KF Pbl, 2. Explain in your own words how binary ionic compounds are named. E. Writing the formula for binary ionic compounds. Given the names of the cations and anions of the combined ionic compound, the formula would be determine by writing the ions and their appropriate charges, then completing the formula by balancing the charges on each ion with subscripts. Fluoride Sulfide lodide Phosphide Oxide Potassium KF Tin (II) Copper (I Aluminum Lead (IV) All
