Chapter 16, Problem 112A

(a)

Interpretation Introduction

Interpretation: The electron dot structures of $\text{I}$ is to be drawn.

Concept introduction: Electron dot structures or Lewis structures represents the bonding present between two atoms of a molecule and also shows the lone pair of electrons present in a particular element.

Answer to Problem 112A

The electron dot structures of $\text{I}$ is shown below.

  

Explanation of Solution

The electronic structure of elements is represented with the help of an electron dot structure. The number of valence electrons present in each element is represented with the help of dots.

For iodine with the atomic number 53, the valence electrons are seven. So, the Lewis dot structure involves seven dots surrounding the symbol of the element, $\text{I}$ .

  

(b)

Interpretation Introduction

Interpretation: The electron dot structures of $\text{Te}$ is to be drawn.

Concept introduction: Electron dot structures or Lewis structures represents the bonding present between two atoms of a molecule and also shows the lone pair of electrons present in a particular element.

Answer to Problem 112A

The electron dot structures of $\text{Te}$ is shown below.

  

Explanation of Solution

For tellurium with the atomic number 52, the valence electrons are six. So the Lewis dot structure involves six dots surrounding the symbol of the element, $\text{Te}$ .

  

(c)

Interpretation Introduction

Interpretation: The electron dot structures of $\text{Sb}$ is to be drawn.

Concept introduction: Electron dot structures or Lewis structures represents the bonding present between two atoms of a molecule and also shows the lone pair of electrons present in a particular element.

Answer to Problem 112A

The electron dot structures of $\text{Sb}$ is shown below.

  

Explanation of Solution

For antimony with the atomic number 51, the valence electrons are five. So the Lewis dot structure involves five dots surrounding the symbol of the element, $\text{Sb}$ .

  

(d)

Interpretation Introduction

Interpretation: The electron dot structures of $\text{Sr}$ is to be drawn.

Concept introduction: Electron dot structures or Lewis structures represents the bonding present between two atoms of a molecule and also shows the lone pair of electrons present in a particular element.

Answer to Problem 112A

The electron dot structures of $\text{Sr}$ is shown below.

  

Explanation of Solution

For strontium with the atomic number 38, the valence electron is two. So, the Lewis dot structure involves two dots surrounding the symbol of the element, $\text{Sr}$ .
