  1. iBar – A Solution To Ionic Naming Kevin Cameron – Chemistry – Peachtree Ridge HS Sarah Eales – Chemistry – Peachtree Ridge HS Christine Wahl – Chemistry – Peachtree Ridge HS

  2. Who We Teach • Peachtree Ridge High School – Gwinnett County • Peachtree Ridge – 3500+ students • 10th Grade Chemistry • Peachtree Ridge has 3 levels: On-level, Pre-AP, & AP • We teach On-level

  3. Common MistakesWe See

  4. Common Errors Given • Magnesium oxide • Dihydrogen dioxide • Copper (II) oxide • Sodium oxide Incorrect Answer • Mg2O2 • HO • Cu2O • NaO2

  5. Our Solution • One method for ionic compounds • Easily identifiable as the solution for ionics • Remove as many “rules” as possible • Needs to work EVERY time

  6. Ionic vs. Covalent

  7. iBar Given Work Area Cation Side Work Area Anion Side Answer

  8. Example: Sodium chloride Sodium chloride +1 Na+ Cl- -1 NaCl

  9. Example: Magnesium oxide Magnesium oxide +2 Mg2+ O2- -2 MgO

  10. Example: Calcium chloride Calcium chloride +2 Ca2+ Cl- -1 X Cl- -2 CaCl2

  11. Example: K2O K2O +2 K+ O2- -2 K+ Potassium oxide

  12. Example: Iron (III) oxide Iron (III) oxide X +3 Fe3+ O2- -2 X +6 Fe3+ -4 X O2- O2- -6 Fe2O3

  13. Example: Cu2O Cu2O +2 Cu O2- -2 + Cu + Copper (I) oxide

  14. Example: Barium and Chlorine Barium chloride +2 Ba2+ Cl- -1 X -2 Cl- BaCl2

  15. Example: Fe3O4 Fe3O4 +2 Ba2+ Cl- -1 X -2 Cl- BaCl2
