  1. ? of the day Day 4 2-28 • 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. Objective Day 4 2-28 How do we name and represent different substances?

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

  4. 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)

  5. 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

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

  7. Ionic Bonding What’s a binary ionic compound? Binary ionic compound – ionic compound consisting of only 2 elements (monatomic ions)

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

  9. Assignment Day 4 2-28 Read section 8.1 (pages 222-225) AND answer #s 1-6 on page 225 –due at end of class Read section 9.1 (pages 264-269) AND answer #s 1-8 on page 269.

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

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

  12. PERIOD 3 did this slide Ionic Bonding Determine the empirical formula for an ionic compound containing… potassium and fluorine calcium and fluorine cesium and sulfur aluminum and oxygen

  13. 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:

  14. Ionic Bonding The weird guys…

  15. PERIOD 6 did this slide Ionic Bonding Throwing in the transition metals: FeO Au2S CuF2 PbS SbF3 NAMING: Work backwards - the overall charge in a compound must be 0

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

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

  18. Quick Talk Anion Electrostatic force Electronegativity Nonpolar covalent bond Stable Penn State Binary ionic compound Chemical bond Cation Octet rule Valence electrons CaF2 (you say the name)

  19. Ionic Bonding Homework: Handout

  20. PERIODS 1 & 5 explain postlab Ionic Bonding

  21. What's a binary ionic compound?

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

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