Comp. 6 Prep

Goal:
Prepare for Monday's test.

Agenda:
Warmup
Study!

Warmup
Create a new journal entry entitled Bonding Self-Assessment. Copy the 7 objectives into your journal and rate your understanding for each objective.
+   if you get it
-    if you sort of get it
0   if you don't get it'
Highlight the objectives you need to work on the most today.

  1. Contrast ionic and covalent compounds in terms of name, metallic character of atoms, bond type, structure, behavior in water, and examples. 
  2. Use electronegativity to predict whether atoms will form ionic bonds or covalent (polar and non-polar) bonds.
  3. Compare and contrast salts and molecules based on observable properties and bond types. 
  4. Draw structural formulas using the HONC 1234 rule.
  5. Predict the ion and/or the number of bonds an atom will form based on its location in the periodic table.
  6. Draw Lewis Structures for a given molecule.
  7. Draw and name the 3D shape of a given molecule using VSEPR. 

Study!

HONC 1234

Goal:
Draw structural formulas using the HONC 1234 rule.

Agenda:
Warmup
Practice
Exit Ticket

Warmup
On the paper I give you, do the following with your elbow partner:
  1. On the bottom of the paper, draw the Lewis dot structures for C, O and H. Forget what those are??….grab your periodic tables and see if you can figure them out!!
  2. On your Lewis dot structures, highlight which electrons you think are bonding in blue and nonbonding in yellow. (Hint: of the three only oxygen has non-bonding electrons)
  3. Write a chemical formula for the molecule. Name this molecule.
  4. Highlight the NON-POLAR covalent bonds yellow, POLAR covalent blue.  Why are there no ionic bonds here?
  5. Draw the dipole moments for each bond +-->
  6. Compare the Lewis dot structures and the structural model. Where are the bonding valence electrons represented on the structural model? Draw them in. 
  7. Add the non-bonding electrons to the structural model. 
  8. Using the model kit what atoms do you think the red, black, and yellow balls represent?  How do you know that? Write this on the back of your paper.
Practice
  1. Open this worksheet in Notability.

Bond Types

Goal:
Use electronegativity to predict whether atoms will form ionic or covalent (polar or nonpolar) bonds.

Agenda
ACT Practice
Notes
Practice
Journal

ACT Practice
You have 10 minutes to answer the ACT practice questions. After we will debrief and discuss challenges and strategies.

Notes
Create a new journal entry entitled "Bond Types." Answer the questions:
  • Why do atoms bond?
  • Define the following bonds and explain when they occur. 
    • Ionic Bond
    • Polar Covalent Bond
    • Nonpolar Covalent Bond

Practice
Make a copy of this worksheet and complete in class. 

Journal
In your journal, answer the following questions:
  1. Identify the metallic character of magnesium and chlorine.
  2. Calculate the electronegativity difference between magnesium and chlorine. 
  3. Write a CER explaining whether you think MgCl2 is ionic, nonpolar covalent, or polar covalent. Use the answers to questions 1 and 2 as evidence.
