Chapter 5, Problem 86A

(a)

Interpretation Introduction

Interpretation:

The noble-gas notation should be used to describe the electron configuration of the element represented by symbol $Kr$.

Concept introduction:

The noble gas used to summarize the electron configuration of an element and provide relevant information about the valence electrons of that element.

Answer to Problem 86A

• The electron configuration will be:

$Kr$ (Krypton): $\left[Ar\right]4s^{2}3d^{10}4p^6$

Explanation of Solution

Given: $Kr$

Explanations: The electron configuration of an element described as the distribution of electrons in orbitals. The noble gas orbital notation of the element uses the electron configuration of the noble gas that is present near before the given element in the periodic table.

The electron configuration will be:

$Kr$ (Krypton): $\left[Ar\right]4s^{2}3d^{10}4p^6$

(b)

Interpretation Introduction

Interpretation:

The noble-gas notation needs to be used to describe the electron configuration of the element represented by symbol $P$.

Concept introduction:

Answer to Problem 86A

• The electron configuration will be:

$P$ (Phosphorous): $\left[Ne\right]3s^{2}3p^3$

Explanation of Solution

Given: $P$

Explanations: The electron configuration of an element described as the distribution of electrons in orbitals. The noble gas orbital notation of the element uses the electron configuration of the noble gas that is present near before the given element in the periodic table

The electron configuration will be:

$P$ (Phosphorous): $\left[Ne\right]3s^{2}3p^3$

(c)

Interpretation Introduction

Interpretation:

The noble-gas notation needs to be used to describe the electron configuration of the element represented by symbol $Zr$.

Concept introduction:

The noble gas used to summarize the electron configuration of an element and provide relevant information about the valence electrons of that element.

Answer to Problem 86A

• The electron configuration will be:

$Zr$ (Zirconium): $\left[Kr\right]5s^{2}4d^2$

Explanation of Solution

Given: $Zr$

Explanations: The electron configuration of an element described as the distribution of electrons in orbitals. The noble gas orbital notation of the element uses the electron configuration of the noble gas that is present near before the given element in the periodic table

The electron configuration will be:

$Zr$ (Zirconium): $\left[Kr\right]5s^{2}4d^2$

(d)

Interpretation Introduction

Interpretation:

The noble-gas notation needs to be used to describe the electron configuration of the element represented by symbol $Pb$.

Concept introduction:

Answer to Problem 86A

• The electron configuration will be:

$Pb$ (Lead): $\left[Xe\right]6s^{2}4f^{14}5d^{10}6p^2$

Explanation of Solution

Given: $Pb$

Explanations: The electron configuration of an element described as the distribution of electrons in orbitals. The noble gas orbital notation of the element uses the electron configuration of the noble gas that is present near before the given element in the periodic table The electron configuration will be:

$Pb$ (Lead): $\left[Xe\right]6s^{2}4f^{14}5d^{10}6p^2$
