6. Classroom Review
Entry
Turned back documents
Grades

7. Reference Table

8. Wrap up Wanted! Poster
You have 12 minutes to finish your wanted poster

9. Ions
Cation: A positive ion
Mg2+, NH4+
Anion: A negative ion
Cl-, SO42-

10. Predicting Ionic Charge
NEITHER
+/-4 +1 -1 +3 -2 -3 +2

11. Determine Charge Ca Se As Br

12. Predicting Ionic Charges
Transition Metals:
Many transition elements
have more than one possible oxidation state.
Iron(II) = Fe2+
Iron(III) = Fe3+

13. Predicting Ionic Charges
Transition Metals:
Some transition elements
have only one possible oxidation state.
Silver = Ag+
Zinc = Zn2+

14. Predicting Ionic Charge
Determining the Charge of a Transition Metal
Find the total charge of the Anion Anion Oxidation # x Anion Subscript
Determine charge of the transition metal Total Anion Charge ÷ Metal Subscript
Transition Metal charge is ALWAYS positive (+)

15. Determine Charge
CuO
Mn3N4
CuCl2
ZnCl2
PdS

16. Revisit Periodic Table Puzzle
Working with your table partner complete number 7-10

17. Ionic Compound Formulas

18. Forming Binary Ionic Compounds
Binary = two elements
Ionic = one metal and one nonmetal
Transfer of electrons
Not called molecules!

19. IUPAC
IUPAC- International Union of Pure and Applied Chemists (created this naming system)

20. Writing Formulas All compounds have a charge of zero.
When writing formulas, all ions have to add up to zero.
Example: Na – Charge of +1
Cl – Charge of -1
NaCl (charges cancel out for 0)

21. Writing Binary Ionics Write each ion (metal first)
Crisscross the charges
Drop the + and –
Write numbers as subscripts

22. Binary Ionic Compounds
Example:
magnesium chloride
Mg+2
Cl-1
MgCl2

23. Why does this work?
MgCl2 means…
Cl-1
Mg+2
Cl-1

24. Binary Ionic Compounds
Example:
barium oxide
Ba+2
O-2
BaO
Ba2O2

25. Practice Sodium bromideNaBr Calcium fluoride CaBr2 Magnesium oxide
Lithium oxide
Aluminum oxide
Magnesium fluoride
Potassium iodide
Aluminum sulfide

26. Forming Ternary Ionics
Contain 3 or more elements
Combination of a metal and a polyatomic ion Refer to page 7 of your reference tables for the list of polyatomic ions.

27. Writing Ternary Ionic Compounds
Write each ion (cation first) --- more than 3 uppercase letters means look at your polyatomic ion list!
Crisscross the charges
Drop the + and –
Write numbers as subscripts
Keep polyatomic ions in parentheses if more than 1(Blue sky rule!)
Never change a polyatomic ion!!!!!

28. Ternary Ionic Compounds
Example:
ammonium chloride
NH4+1
Cl-1
NH4Cl

29. Ternary Ionic Compounds
Example:
lithium carbonate
Li+1
CO3-2
Li2CO3

30. Ternary Ionic Compounds
Example:
calcium hydroxide
Blue Sky Rule!!!
Ca+2
OH-1
Ca(OH)2

31. Why does this work?
Ca(OH)2 means…
OH-1
Ca+2
OH-1

32. Practice Magnesium hydroxide Potassium sulfate  Sodium phosphate 
Calcium nitrate 

33. Stock System for Ionic Compounds
Some metals can have more than one oxidation state (i.e. transition metals)
Use roman numerals
Examples:
Copper (I) chloride
Cu+1
Cl-1
CuCl
Copper (II) chloride
CuCl2
Cu+2
Cl-1

34. Practice Mercury (II) oxide  Vanadium (V) bromide 
Copper (I) oxide 
Tin (IV) bromide 

35. NB Raffle

36. Fist to Five
5- I could teach it 4 – I’ve got it 3 – I need to study some 2 – I need to study AND come to tutoring 1 – I have no idea what I am doing
