Ionic Compounds Practice

1. Ionic Compounds Practice

2. Objective • Today I will be able to: • Correctly name and write the formula for ionic compounds using the classical and stock method • Evaluation/ Assessment • Informal assessment – Listening to group interactions as they complete the naming and writing formulas worksheets. • Formal Assessment – Analyzing student responses to the exit ticket and naming/writing formulas worksheet • Common Core Connection • Build Strong Content Knowledge • Look for and express regularity in repeated reasoning

3. Lesson Sequence • Warm – Up • Elaborate: Writing Ionic Formulas Practice • Formal assessment • Explain: Classical Naming Notes • Elaborate: Naming Ionic Compounds Practice • Formal assessment • Elaborate: Writing formulas practice • Evaluate: Exit ticket • Formal assessment

4. Warm-Up • What are ionic compounds composed of? • What are the properties of an ionic compound? • Name the following ionic compounds using the stock system • FePO4 • KC2H2O2 • PbCl2

5. Objectives • Today I will be able to: • Correctly name and write the formula for ionic compounds using the classical and stock method

6. Homework • Study the Polyatomic Ions • STEM Fair Abstract Due Monday December 9 • Finish classwork

7. Agenda • Warm – Up • Ionic Formulas Notes Continued • Writing Ionic Formulas from Names Practice • Classical Naming Notes • Classical Naming Practice • Writing Ionic Formulas Practice 2 • Exit Ticket

8. Naming Ionic Compounds • Standard Naming Rules • Write the full name of the metal first • Then write the second element, take off the ending and add the suffix –ide • If the second ion is a polyatomic ion, use the full name of the ion • Examples • CaO – Calcium Oxide • BaCl2 – Barium Chloride

9. Naming Ionic Compounds • Exceptions • Transition metals can have multiple oxidation numbers • Standard naming rules apply but we need to account for the oxidation number • Two Naming Systems • Classical • Stock

10. Stock Method for transition metals • Stock method - use a roman numeral • Examples • FeCl3 – Iron(III) Chloride • FeCl2 – Iron (II) Chloride • PbCl4 – Lead(IV) Chloride • Later we will discuss an additional method called the Classical Method • Stock is more standard

11. Writing Ionic Formulas from Names Practice Complete the practice at your desk. Ask Mr. Klotz for help if you have questions. We will review selected responses as a class.

12. Classical Naming Notes

13. Classical Naming System • These rules still apply: • Then write the second element, take off the ending and add the suffix –ide • If the second ion is a polyatomic ion, use the full name of the ion

14. Classical Naming System • The name of the metal for the elements in the d-block and f-block changes • Use a latin stem • Example: Copper • Stem: Cupr – • Cuprous – Cu+1 • Cupric – Cu+2 • CuCl2 = Cupric Chloride

15. Suffixes • ous is associated with the lower oxidation number - ic is assoiciated with the larger oxidation number

16. Examples • FeCl2 • Ferrous Chloride • FeCl3 • Ferric Chloride

17. Classical Naming Practice Name the ionic compounds containing polyatomic ions using the classical method. Selected responses will be reviewed in class

18. Writing Ionic Formulas Practice 2 Complete the practice at your desk. Ask Mr. Klotz for help with the questions.

19. Exit Ticket • What’s wrong with the following formula/ name of compound? Mg2Cl MgSO4 – Magnesium sulfide Baride Chlorine
