Calculate the difference in electronegativity and classify (circle) the bonding

Question

Calculate the difference in electronegativity and classify (circle) the bonding for the following as ionic, covalent, or polar covalent. Use the electronegativity values from Figure. 8.7 (Pg. 310 of textbook). (a) F-F Answer: Electronegativity difference = ____; ionic/nonpolar covalent/polar covalent bond.

(b) C-F Answer: Electronegativity difference = ____; ionic/nonpolar covalent/polar covalent bond.

(c) Na-Cl Answer: Electronegativity difference = ____; ionic/nonpolar covalent/polar covalent bond.

(d) N-I Answer: Electronegativity difference = ____; ionic/nonpolar covalent/polar covalent bond.

(e) K-Cl Answer: Electronegativity difference = ____; ionic/nonpolar covalent/polar covalent bond.
