Week 11: 10/16
Monday -
In Class: Students received new seating assignments. Students were informed of new bathroom policy (each student gets 2 bathroom passes/quarter to be used for emergencies). Went over lockdown procedures. Students took teacher-led notes on the board and copied chart at the end of Ch.8.1 (PowerPoint Slide #7)
Homework: Read Ch. 8.1
Tuesday -
In Class: Went over single, double, and triple bonding of covalent bonds and Electron Dot Structures. Also went over dot structures for compounds with charges. Completed in-class practice worksheets and 'Covalent Bonding and E-Dot Structure Practice Worksheet'.
Homework: Read Ch. 8.2
Wednesday/Thursday -
In Class: Bellwork we defined polar covalent, nonpolar covalent, polar molecule, and dipole and also copied the "Electronegativity Differences and Bond Type" (Table 8.4) on page 248 or page 225 (depending on the book you have) in their notes. They were given the Electronegativity Values Periodic Table as well. Then students completed the "Quantitative Analysis and Chemical Bonding Lab".
Homework: Lab Write-Up
Friday -
In Class: Worked on Calculating Bond Polarity Concepts. Collected Lab Books
Homework: None
Rules for drawing Covalent Electron Dot Structures
Calculate how many total valence electrons are needed for your structure
Put single bonds connecting the central atom to your other atoms (connect all the atoms with single bonds).
Fill in the octets of your outer atoms first, then fill in your central atom
Check to see if all atoms have a stable, full octet
If an atom does not have a full octet rearrange the electrons to make all atoms have a full octet.
**Some molecules do not have a full 8 octet for each atom. Some molecules have less and some have more. You will only need to be able to do the structures that have full octets**
