iBar – A Solution To Ionic NamingKevin Cameron – Chemistry – Peachtree Ridge HSSarah Eales – Chemistry – Peachtree Ridge HSChristine Wahl – Chemistry – Peachtree Ridge HS
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
Common Errors You See in Naming Ionics
Common Misteaks Mistakes We SeeGiven• Magnesium oxide• Dihydrogen dioxide• Copper (II) oxide• Sodium oxide
Incorrect Answer• Mg2O2
• HO• Cu2O
• NaO2
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
Ionic vs. Covalent
