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

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

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

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