    1. Writing Formulas and Naming Ionic Compounds

    2. Binary Ionic Compounds Binary means 2. A binary ionic compound is composed of 2 different elements. 1 metal and 1 nonmetal. Examples NaCl, K2O, Al2S3. To name an ionic compound from its formula, follow these steps: Al2S3 1. Name the metal cation aluminum 2. Name the non-metal anion, but change its ending to ide Example: sulfur becomes sulfide Al2S3- aluminum sulfide

    3. Examples fluorine chlorine iodine nitrogen oxygen phosphorus selenium bromine carbon fluoride chloride iodide nitride oxide phosphide selenide bromide carbide

    4. You try Name the following binary ionic compounds: 1. KBr 2. BaCl2 3. Na3N 4. Mg3P2 5. AlF3 6. NaCl Answers Potassium bromide Barium chloride Sodium nitride Magnesium phosphide Aluminum fluoride Sodium chloride

    5. Writing formulas from the names Follow the following steps. 1. Write the most probable ions for each elements name. potassium oxide K+1 O-2 2. Use the criss-cross method or find the least common multiple of the two charges. K+1 O-2 K2 O 3. If you use the criss-cross method, remember to reduce the subscripts if needed. Mg2O2 ? MgO
