Chapter 1, Problem 1.7YT

Interpretation Introduction

Interpretation:

Difference in electronegativity between the elements in $\text{NaCl}$ and in ${\text{CH}}_{\text{4}}$ is to be determined.

Concept introduction:

The ability to attract electrons in covalent bonds is defined as the element’s electronegativity (EN).

Electronegativity of Na is $0.\text{93}$, and that for Cl is $\text{3}.\text{16}$. Electronegativity of C is $\text{2}.\text{55}$, and that for H is $\text{2}.\text{2}0$.

When elements in a compound have a large difference in electronegativity, ionic bonding can occur.

When elements in a compound have a small difference in electronegativity, covalent bonding can occur.
