We will have to calculate the electronegativity difference of the elements forming the bond:
(ΔEN) Bond Classification
Zero (0.0) Pure Covalent
Small (0.1 – 0.4) Nonpolar Covalent
Intermediate (0.4 – 1.7) Polar Covalent
Large (Greater than 1.7) Ionic
Determine the bond type between each of the following pairs.
a) H and H
b) N and O
c) C and I
d) K and O
