Chapter 8.6, Problem 1PPC

Interpretation Introduction

Interpretation: The nonmetal elements that form compounds with the highlighted metal and have the most percent ioniccharacter are to be arranged in the increasing order. The figure is as follows:

Concept introduction:

Bond enthalpy: It is the energy required to break a bond of 1mole of a substance. It is expressed in $\text{KJ}/\text{mol}$.

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

The compounds can be distinguished, based on the electronegativity difference as follows:

When $\text{electronegativity difference}<0.5$, the compound is nonpolar.

When $\text{0}\text{.5}<\text{electronegativity difference}<2$, the compound is polar-covalent.

When $\text{electronegativity difference}>2$, the compound is ionic.
