Week of Feb 11

Monday: Candy modeling.  Swedish fish and toothpicks to illustrate trig bipyramidal and octahedral.  Then marshmallows, life saver gummies and twizzlers to illustrate sigma and pi bonds.

Tuesday: Electronegativity, polarity, polar bonds, percent ionic character, polar molecules, lecture and practice. Handed out a practice test.

Wednesday: We started with some free response problems from the practice test I handed out yesterday and then I lectured on factors that contribute to acid strength, Lewis Acids/Bases and coordinate covalent bonding. (SmartBoard Notes)  Tomorrow we’ll do a little more with this!

Thursday:  I asked you guys to do more on the “modeling lab” and alot of you were having a hard time relating shape and hybridization so I went over that.  Then we did a review of coordinate covalent bonding terms and did this worksheet. The last 40 min you spent making a valentine from a Lewis Acid to a ligand.

Friday: Beer’s Law Lab  Homework: Transition metal movie   Announcement: Test is THURSDAY, Feb 21 despite what it says on your calendar!

Week of Feb 4

  • Monday: Ionic Bond strength, melting points of ionic materials and metals + calculations of lattice energy using Born-Haber Cycle (continued in this packet).  Here’s the Smartboard notes (includes all notes from last week’s bonding lectures, too)
    • Also handed tests back and there were some questions about what the AP exam will really be like.  Here’s the info
    • Homework: Suggested you do one of the Born-Haber cycle problems in the packet.  Answers are on the last page.
    • Test on Wed.  Topics to be covered are:
        1. Ionic radius explanations
        2. Transition metal ion prediction / electron configurations
        3. Explain trend in ionic melting point
        4. Explain trend in metal melting point
        5. Draw and label Born Haber cycle
        6. Define lattice energy, heat of formation, heat of sublimation, bond enthalpy, ionization energy, electron affinity.
        7. Calculate Lattice energy
