Presentation Transcript

  1. Catalyst – October 1.1x20, 2009Please take HW out. Hold onto your element. • Show the IONIZATION of an Aluminum atom. (Write one equation) • Using Kriss Kross, write the formulas for the following: a) Ga O b) Na CO3 c) Cl Mg

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

  3. Ionization Energy ReviewTry these on your own! • What has a higher 4th ionization energy? • Nitrogen or Fluorine? • What has a higher 2nd ionization energy? • Aluminum or Silicon?

  4. GEE Test Practice:

  5. Today’s Objectives • SWBAT write formulas for ionic compounds. • SWBAT name ionic compounds.

  6. Ionic Formula Practice • Write formulas for the compounds that will form from the following ions. (Just use Kriss Kross!) • Na1+ F1- • Al3+ (NO3)1- • (NH4)1+ Cl1- • Be2+ O2-

  7. 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!) • Cu(II) NO3 • Mg Se • SO4 B • Ca Br

  8. Naming Ionic Compounds

  9. What do you see? Copy the table into your notes and fill in the question marks with what you think is correct.

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

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

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

  13. ZnO Naming Ionic Compounds

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

  15. ZnO Naming Ionic Compounds

  16. ZnO Zinc Oxide Naming Ionic Compounds

  17. CaCl2 Naming Ionic Compounds

  18. CaCl2 Calcium Chloride Naming Ionic Compounds

  19. Al2O3 Naming Ionic Compounds

  20. Al2O3 Aluminum Oxide Naming Ionic Compounds

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

  22. Ionic Cheat Sheet! Naming Ionic Compounds

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

  24. The way you use it… Naming Ionic Compounds

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

  26. BaCO3 Naming Ionic Compounds

  27. BaCO3 Barium Naming Ionic Compounds

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

  29. BaCO3 Barium Naming Ionic Compounds

  30. BaCO3 Barium Carbonate Naming Ionic Compounds

  31. AlPO3 Naming Ionic Compounds

  32. AlPO3 Aluminum Naming Ionic Compounds

  33. AlPO3 Aluminum Phosphite Naming Ionic Compounds

  34. H3PO4 Naming Ionic Compounds

  35. H3PO4 Hydrogen Naming Ionic Compounds

  36. H3PO4 Think: H1+, we have 3 which means +3, where will PO4 be? Naming Ionic Compounds

  37. H3PO4 Hydrogen Phosphate Naming Ionic Compounds

  38. FeSO4 Naming Ionic Compounds

  39. FeSO4 Notice Iron appears in +2 and +3… Naming Ionic Compounds

  40. FeSO4 Sulfate Naming Ionic Compounds

  41. FeSO4 Since Sulfate is -2, Fe must be +2 Naming Ionic Compounds

  42. FeSO4 Iron(II) Sulfate Naming Ionic Compounds

  43. FeSO4 Iron(II) Sulfate or Ferrous Sulfate Naming Ionic Compounds

  44. Practice Time!

  45. Write the formulas and names for the following elements. 1.Ga NO3 2. K S 3. Mg O Exit Ticket
