Chapter MS, Problem 18PQ

Interpretation Introduction

Interpretation:

The number of valence electrons that are represented in Lewis electron-dot structure of ${\text{SO}}_2$ has to be determined.

Concept Introduction:

The diagrams that represent type of bonding between atoms in molecule and number of lone pairs present in molecule are known as Lewis electron-dot structures. Such structures are also known as Lewis dot diagrams, Lewis dot formulas or Lewis structures.

The formula to calculate total valence electrons in ${\text{SO}}_2$ is as follows:

  $\text{Total valence electrons}\left(\text{TVE}\right)=\left(\begin{array}{c}\left(\text{1}\right)\left(\text{Valence electrons of S}\right)+\\ \left(\text{2}\right)\left(\text{Valence electrons of O}\right)\end{array}\right)$        (1)
