Interpretation Introduction

Interpretation:

Thegiven elements are to be arranged in the order of increasing ionic percent character.

Concept introduction:

Electronegativity is the measure of the ability of a cation to pull a pair of electrons toward itself.

The compounds can be distinguished from the electronegativity difference as follows:

When electronegativity difference is less than 0.5, the compound is no-polar.

When electronegativity difference is between 0.5 and 2, the compound is polar-covalent.

When electronegativity difference is greater than 2, the compound is ionic.
