Electronegativity Difference
Illustrating Ionic and Covalent
Bonds
Ionic vs. Covalent Pre-lab
• Objectives
▫ Today I will be able to:
▫ Name ionic and covalent compounds correctly
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 (1)
• What happens to the electrons in an ionic bond?
• What happens to the electrons in a covalent
bond?
• What is the difference between a polar bond and
a nonpolar bond?
• Which type of bond is the strongest?
Warm – Up (2)
• Take everything off of your desk except for a
writing utensil for your polyatomic ions quiz!
Warm – Up (3)
• Determine the type of bond using the
electronegativity value table
• O-H
• Na-F

Listen to Ms. Ose’s example and
then complete the practice at your
desk. Select responses will be
reviewed
