2 Catalyst – October 1.1x20, 2009 Please take HW out. Hold onto your element. 1. Show the IONIZATION of an Aluminum atom. (Write one equation) 2. Using Kriss Kross, write the formulas for the following: a) Ga O b) Na CO 3 c) Cl Mg

3 Today’s Agenda  Catalyst  More Ionic Review Practice  Naming Ionic Compounds  Unit 3 Tracking/Work Time  Exit Question HOMEWORK: Personals Ad Project

4 Ionization Energy Review Try these on your own! 1. What has a higher 4 th ionization energy?  Nitrogen or Fluorine? 2. What has a higher 2 nd ionization energy?  Aluminum or Silicon?

5 GEE Test Practice:

6 Today’s Objectives  SWBAT write formulas for ionic compounds.  SWBAT name ionic compounds.

7 Ionic Formula Practice  Write formulas for the compounds that will form from the following ions. (Just use Kriss Kross!) 1. Na 1+ F Al 3+ (NO 3 ) (NH 4 ) 1+ Cl Be 2+ O 2-

8 Ionic Formula Practice  Write formulas for the compounds that will form from the following elements and polyatomics. Now, YOU have to create the ion! (And use Kriss Kross!) 1. Cu(II) NO 3 2. Mg Se 3. SO 4 B 4. Ca Br

9 Naming Ionic Compounds

10 What do you see? Copy the table into your notes and fill in the question marks with what you think is correct. Formula for Ionic Compound Name for Ionic Compound NaClSodium chloride CaCl 2 Calcium chloride KBrPotassium bromide MgF 2 ??? NaBr???

11 Naming Ionic Compounds KEY POINT: Rules of naming… 1)Write name of first element (metal). 2)Second element ends in -ide. 3)Ignore subscripts!

12 Naming Ionic Compounds Draw a mental line between the ions. Na + Cl -

13 Naming Ionic Compounds Binary Ionic Compound – an ionic compound composed of two elements

14 Naming Ionic Compounds ZnO

15 Naming Ionic Compounds KEY POINT: Rules of naming… 1)Write name of first element (metal). 2)Second element ends in -ide. 3)Ignore subscripts!

16 Naming Ionic Compounds ZnO

17 Naming Ionic Compounds ZnO Zinc Oxide

18 Naming Ionic Compounds CaCl 2

19 Naming Ionic Compounds CaCl 2 Calcium Chloride

20 Naming Ionic Compounds Al 2 O 3

21 Naming Ionic Compounds Al 2 O 3 Aluminum Oxide

22 Naming Ionic Compounds Ternary Ionic Compound – an ionic compound with more than 2 elements

23 Naming Ionic Compounds Ionic Cheat Sheet!

24 Naming Ionic Compounds Do not lose this…you will need it the rest of your life (in my class).

25 Naming Ionic Compounds The way you use it…

26 Naming Ionic Compounds 1) Look up the ions on the cheat sheet and write the words next to them.

27 Naming Ionic Compounds BaCO 3

28 Naming Ionic Compounds BaCO 3 Barium

29 Naming Ionic Compounds If the first element is +2, where should we find the second? (Remember, charges must balance to zero!)

30 Naming Ionic Compounds BaCO 3 Barium

31 Naming Ionic Compounds BaCO 3 Barium Carbonate

32 Naming Ionic Compounds AlPO 3

33 Naming Ionic Compounds AlPO 3 Aluminum

34 Naming Ionic Compounds AlPO 3 Aluminum Phosphite

35 Naming Ionic Compounds H 3 PO 4

36 Naming Ionic Compounds H 3 PO 4 Hydrogen

37 Naming Ionic Compounds H 3 PO 4 Think: H 1+, we have 3 which means +3, where will PO 4 be?

38 Naming Ionic Compounds H 3 PO 4 Hydrogen Phosphate

39 Naming Ionic Compounds FeSO 4

40 Naming Ionic Compounds FeSO 4 Notice Iron appears in +2 and +3…

41 Naming Ionic Compounds FeSO 4 Sulfate

42 Naming Ionic Compounds FeSO 4 Since Sulfate is -2, Fe must be +2

43 Naming Ionic Compounds FeSO 4 Iron(II) Sulfate

44 Naming Ionic Compounds FeSO 4 Iron(II) Sulfate or Ferrous Sulfate

45 Practice Time!

46 Exit Ticket Write the formulas and names for the following elements. 1. Ga NO 3 2. K S 3. Mg O
