Yesterday, the class did not have enough time to completely go over covalent bonding, so we finished the notes today (posted in the unit 7 notes folder). In addition we redid yesterdays homework about Lewis Structures in class, to serve as a good review about Lewis Structures. Finally Mrs. Friedmann began the worksheets "What is a Bond?" which we are suppose to complete for homework.
Notes Review...
- Here is a good review about Lewis Structures from one of the Crash Courses Videos...
Here are the exceptions to the octet rule discussed today...
- Hydrogen needs 2 electrons not 8
- Boron needs 6 electrons not 8
- Everything including the third period and down the periodic table can hold more than 8 electrons if it has to.
Homework..
1) Finish the "What is a Bond?" pair of worksheets we began in class today. Due tomorrow.
2) WebAssign 7.1a-Covalent Bonding and LED -- due tonight by 11:59 pm.
3) Watch the two videos posted in the Unit 7 box: "Covalent Bonding" and "Bonding Models and Lewis Structures". Take notes on both videos in your journals, to be checked in tomorrow.
4) Quiz tomorrow on bonding and Lewis Structures!
