  3. Finishing Up Ionic Bonds and Project Time • Objective: • SWBAT find formula and name ionic bonds • Catalyst: • What is an ionic bond? • What is the oxidation number of Bromine? • What is the formula for the ionic compound formed between Magnesium and Fluorine?

  4. Speed Dating Project!

  5. Ca2+As3- Kris Kross Method! Ca3As2

  6. Which charge ALWAYS comes first? POSITIVE!!!

  7. Which type of element ALWAYS comes first? METAL!!!

  8. K F Ba N Ga O Ca Cl K Si Co I

  16. KF Ba3N2 Ga2O3 CaCl2 K Si Co I

  17. KF Ba3N2 Ga2O3 CaCl2 K1+Si4- Co I

  18. KF Ba3N2 Ga2O3 CaCl2 K4Si Co I

  19. K F Ba N Ga O Ca Cl K Si Co I You don’t know about transition metals! So.. the problem must tell you the number of electrons. Cobalt (II) means that Cobalt gives up 2 electrons

  20. K F Ba N Ga O Ca Cl K Si Co2+I1-

  21. For POLYATOMICS it gets a bit more complex Pb4+SO42- Pb2(SO4)4 NH41+PO43- (NH4)3 PO4

  22. Naming Ionic Compounds

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

  24. Write name of first element (metal). • Second element ends in -ide. • Ignore subscripts! Naming Ionic Compounds

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

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

  27. ZnO Naming Ionic Compounds

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

  36. The way you use it… Naming Ionic Compounds

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

  38. BaCO3 Naming Ionic Compounds

  39. BaCO3 Normally the first element is the first piece and the rest is the second piece. Naming Ionic Compounds
