1. Electronegativity Difference Illustrating Ionic and Covalent Bonds Ionic vs. Covalent Pre-lab

2. Objectives Today I will be able to:
Demonstrate knowledge of 15 polyatomic ions on a quiz
Determine if a compound is nonpolar covalent, polar covalent or ionic based off of the electronegativity difference between bonds.
Illustrate the transfer and sharing of electrons in ionic and covalent bonds by using lewis structures
Design a data table for the ionic vs. covalent compounds lab. .
Informal assessment – monitoring student interactions as they complete the practice problems and the pre-lab
Formal assessment – analyzing student responses to the exit ticket and practice problems
Common Core Connection
Reason abstractly and quantitatively
Look for and express regularity in repeated reasoning

3. Warm-Up – Part 1
Take one of all of the worksheets up front and staple them together!

4. Warm – Up – Part 2
Take everything off of your desk except for a writing utensil for your polyatomic ions quiz!
