Question

Here is the question:

Classify the bonds formed between each pair of elements based on electronegativity values in the following table:

The difference in electronegativity between the two elements in a bond can be used to predict bond type.

As a general rule, if the difference is zero, the bond is nonpolar covalent,

if the difference is greater than two, the bond is substantially ionic,

and if the difference is greater than zero but less than two, the bond is polar covalent.

Here is my answer that I can't figure out why it is wrong:

Any help would be greatly appreciated. Thank you!!

Element Sc Be H P S I Br Cl O F Electronegativity 1.3 1.5 2.1 2.1 2.5 2.5 2.8 3.0 3.5 4.0

your correction is Be-Cl = 3-1.5 = 1.5

polar covalent .rest all are correct GOOD job!
