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

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?
