Chapter 3, Problem 48A

(a)

Interpretation Introduction

Interpretation: The formula for simple ion formed by the element having $\text{53}$ an atomic number needs to be explained.

Concept Introduction :

Element- An element is formed by a similar type of atom. The atom of an element consists of three subatomic particles electron, protons, and neutrons where the protons number explains the atomic number of the element.

By the loss or gain, an element is changed into its ionic form.

Answer to Problem 48A

The atomic number $\text{53}$ is for ${\text{I}}_{\text{2}}$ and the formula for the simple ion that the element is most likely to form is ${\text{I}}^{\text{1-}}$ .

Explanation of Solution

Iodine behaves like a strong reducing agent. It easily gets stable by the formation of the iodide ion.

Iodine generally exists in molecular form and it combines with iodides to form poly iodine.

(b)

Interpretation Introduction

Interpretation: The formula for simple ion form by the element having $\text{38}$ an atomic number needs to be explained.

Concept Introduction :

Element- An element is formed by a similar type of atom. The atom of an element consists of three subatomic particles electron, protons, and neutrons where the protons number explains the atomic number of the element.

By the loss or gain, an element is changed into its ionic form.

Answer to Problem 48A

The atomic number $\text{38}$ is for $\text{Sr}$ and the formula for the simple ion that the element is most likely to form is ${\text{Sr}}^{\text{2+}}$ .

Explanation of Solution

Strontium is placed in group two of the periodic table. The most stable charge of group two is $2+$ for the stable configuration hence strontium gives two electrons from its outermost shell and gets changed into ${\text{Sr}}^{\text{2+}}$ .

(c)

Interpretation Introduction

Interpretation: The formula for simple ion formed by the element $\text{55}$ having an atomic number needs to be explained.

Concept Introduction :

Element- An element is formed by a similar type of atom. The atom of an element consists of three subatomic particles electron, protons, and neutrons where the protons number explains the atomic number of the element.

By the loss or gain, an element is changed into its ionic form.

Answer to Problem 48A

The atomic number $\text{55}$ is for $\text{Cs}$ and the formula for the simple ion that the element is most likely to form is ${\text{Cs}}^{\text{1+}}$ .

Explanation of Solution

Cesium is placed in group one of the periodic table. The most stable charge of group one is $1+$ for the stable configuration hence cesium gives one electron from its outermost shell and changes into ionic form.

(d)

Interpretation Introduction

Interpretation: The formula for simple ion form by the element having $\text{88}$ an atomic number needs to be explained.

Concept Introduction :

Element- An element is formed by a similar type of atom. The atom of an element consists of three subatomic particles electron, protons, and neutrons where the protons number explains the atomic number of the element.

By the loss or gain, an element is changed into its ionic form.

Answer to Problem 48A

The atomic number $\text{88}$ is for $\text{Ra}$ and the formula for the simple ion that the element is most likely to form is ${\text{Ra}}^{\text{2+}}$ .

Explanation of Solution

Radium is placed in group two of the periodic table. The most stable charge of group two is $2+$ for the stable configuration hence radium gives two electrons from its outermost shell and forms radium ion.

(e)

Interpretation Introduction

Interpretation: The formula for simple ion form by the element having $\text{9}$ atomic number needs to be explained.

Concept Introduction :

Element- An element is formed by a similar type of atom. The atom of an element is consisting of three subatomic particles electron, protons, and neutrons. Where the protons number explains the atomic number of the element.

By the loss or gain of electron, an element is change into its ionic form.

Answer to Problem 48A

The atomic number $\text{9}$ is for $\text{F}$ and the formula for the simple ion that the element is most likely to form is ${\text{F}}^{\text{1-}}$ .

Explanation of Solution

Fluorine behaves like a strongly electronegative element in the periodic table. It can easily accept electrons and get stable by the formation of the fluoride ion.

(f)

Interpretation Introduction

Interpretation: The formula for simple ion form by the element having $\text{13}$ an atomic number needs to be explained.

Concept Introduction :

Element- An element is formed by a similar type of atom. The atom of an element is consisting of three subatomic particles electron, protons, and neutrons. Where the protons number explains the atomic number of the element.

By the loss or gain an element is change into its ionic form.

Answer to Problem 48A

The atomic number $\text{13}$ is for $\text{Al}$ and the formula for the simple ion that the element is most likely to form is ${\text{Al}}^{\text{3+}}$ .

Explanation of Solution

Aluminum has $\text{3}$ valance electrons in its outer shell so it can give three electrons and converted into aluminum ion.
