  1. ? of the day Day 2 4-2 • Lewis Dot structure for francium bonded to chlorine: • 2. Ionic bonds most commonly form between??? • 3. Where would you find elements that form cations on the periodic table?

  2. Review ______ compounds break apart into ______ when dissolved in water and conduct electricity. Ionic ions

  3. Objective Day 5 3-1 How do we name and represent different substances?

  4. REVIEW Ionic Bonding Ionic bonds – Chemical bonds that result from the electrical attraction between large numbers of cations and anions Cation – ? Anion – ?

  5. REVIEW Ionic Bonding Ionic bonds most commonly form between …? Ionic bonds are made up of charged pieces (ions) … Ions can be made up of single atoms or groups of atoms bonded together (polyatomic ions)

  6. Ionic Bonding Binary ionic compound – ionic compound consisting of only 2 elements (monatomic ions) Naming: Name the cation and add an ide ending to the anion

  7. Ionic Bonding Examples: sodium and chlorine form… sodium chloride magnesium and oxygen form… magnesium oxide

  8. Naming Practice Bromine bonds with sodium Cesium bonds with oxygen Silver bonds with fluorine Sodium bromide Cesium oxide Silver fluoride

  9. Naming Practice chlorine bonds with lithium magnesium bonds with sulfur aluminum bonds with oxygen Lithium chloride Magnesium sulfide Aluminum oxide

  10. Ionic Bonding Binary ionic compound = ? Binary ionic compound – ionic compound consisting of only 2 elements (monatomic ions)

  11. Ionic Bonding Problem… names do not directly indicate ratio of ions… Answer… empirical formula Li2O NaCl MgF2 Determining formulas – Crisscross method

  12. Ionic Bonding Determining formulas – Crisscross method 1. determine charges 2. Take away the +/- and crisscross them to determine subscripts

  13. Ionic Bonding Determine the empirical formula for an ionic compound containing… potassium and fluorine calcium and fluorine cesium and sulfur aluminum and oxygen

  14. Question of the Day • Name the compounds formed when the following elements bond: • Calcium and fluorine • Chlorine and strontium • Silver and oxygen • Write the formulas for the following compounds: • Lithium bromide • Barium chloride • Sodium oxide Day 3 4-3

  15. Ionic Bonding Homework: Day 2 4-2 Read / review section 9.1 and complete #s 3-8 on page 269

  16. Review • Get out the new notes. What is a binary ionic compound?

  17. Ionic Bonding Throwing in the transition metals: Use roman numerals if more than one charge is possible Roman numeral = charge, if none use sheet, then same as binary ionic compounds Ion Sheet NAMING: FORMULAS:

  18. Ionic Bonding The weird guys…

  19. Ionic Bonding Throwing in the transition metals: FeO Au2S CuF2 PbS SbF3 NAMING: Work backwards - the overall charge in a compound must be 0

  20. Ionic Bonding • Throwing in the transition metals: • Lead II oxide • Silver bromide • Ferric Chloride Formulas:

  21. Practice Formulas: calcium fluoride cobalt III oxide cuprous chloride NAMING: Rb2S NiO CuF

  22. Question of the Day = ATB Formulas: copper II fluoride magnesium oxide Day 4 4-4 NAMING: Rb2S Fe2O3

  23. Quarter 3 ATBs

  24. Quick Talk Anion Electrostatic force Electronegativity Nonpolar covalent bond Binary ionic compound Chemical bond Cation Octet rule Valence electrons acids

  25. Practice Formulas: Beryllium sulfide iron III sulfide cuprous fluoride NAMING: Au2S SrO AgF

  26. Recs.

  27. Handouts

  28. Throwing in the transition metals: FeO Au2S CuF2 PbS SbF3 NAMING: Work backwards - the overall charge in a compound must be 0

  29. Throwing in the transition metals: • Lead II oxide • Silver bromide • Ferric Chloride Formulas:
