1 BELL RINGER What would be the formula for a BINARY IONIC COMPOUND formed from each pair of elements? Refer to the COMMON ION Periodic Table for charges. 1.Calcium and Fluorine 2. Aluminum and Sulfur 1 ( +2) 2 (-1) 2(+3) 3(-2) Ca F Al S CaF 2 Al 2 S 3 What should we call these compounds?

2 Naming Binary Ionic Compounds

3 Binary Ionic Compounds I CAN name a binary ionic compound from its properly written formula.

4 What are BINARY Ionic Compounds? The formulas we’ve written to this point represent BINARY IONIC compounds: – Consist of only TWO DIFFERENT ELEMENTS. – Contain a + METAL CATION and a – NONMETAL ANION.

5 Naming a Binary Ionic Compound To name a binary ionic compound: 1. Name the + METAL ION first by its ELEMENT NAME. 2. Name the – NON-METAL ION last by its ELEMENT NAME except: – Change the ENDING to “IDE”. If the name ends in “INE” just switch to “IDE”. If the name ends in something else, you may have to DROP PART OF THE NAME before changing to IDE.

6 EXAMPLES Chlorine – ends in “INE” – becomes What does Bromine become? What about elements that do not end in INE? – Oxygen becomes – Sulfur becomes – Phosphorus becomes – Nitrogen becomes – Arsenic becomes CHLORIDE BROMIDE OXIDE SULFIDE PHOSPHIDE NITRIDE ARSENIDE

7 Practice Problems Name these compounds: NaCl CaF 2 Ba 3 P 2 K 3 N AlAs SODIUM CHLORIDE CALCIUM FLUORIDE BARIUM PHOSPHIDE POTASSIUM NITRIDE ALUMINUM ARSENIDE

8 More Practice Problems Determine the FORMULA for the binary ionic compound formed by each pair of atoms, then NAME the compound. 1. Rubidium and Fluorine6. Francium and Oxygen 2. Potassium and Phosphorus7. Calcium and Bromine 3. Radium and Nitrogen8. Strontium and Arsenic 4. Lithium and Sulfur9. Aluminum and Selenium 5. Boron and Fluorine10. Rubidium and Astatine

9 1. RbF Rubidium Fluoride 2. K 3 P Potassium Phosphide 3. Ra 3 N 2 Radium Nitride 4. Li 2 SLithium Sulfide 5. BF 3 Boron Fluoride 6. Fr 2 OFrancium Oxide 7. CaBr 2 Calcium Bromide 8. Sr 3 As 2 Strontium Arsenide 9.Al 2 Se 3 Aluminum Selenide 10. RbAtRubidium Astatide
