Chapter 3, Problem 3.29E
Interpretation Introduction

(a)

Interpretation:

The symbol and name for an element that contains one unpaired 5p electron is to be predicted.

Concept introduction:

The elements in a modern periodic table are arranged in increasing order of their atomic number. In the modern periodic table, the horizontal rows are known as periods and vertical columns are known as groups. There are 7 periods and 18 groups in modern periodic table.

Answer to Problem 3.29E

The name of an element that contains one unpaired 5p electron is indium and its symbol is In respectively.

Explanation of Solution

Electronic configuration tells about the arrangement of the electrons in each subshell and orbit of an atom.

The electronic configuration for an element that contains one unpaired 5p electron would be 1s22s22p63s23p64s23d104p65s24d105p1. Thus, the total number of electrons is 49. The number of electrons corresponds to the atomic number of an element. Therefore, the atomic number of an element is 49 that is indium. The symbol used for indium is In.

Conclusion

The name of the element that contains one unpaired 5p electron is indium and its symbol is In respectively.

Interpretation Introduction

(b)

Interpretation:

The symbol and name for an element that contains a half-filled 5s electron is to be predicted.

Concept introduction:

The elements in a modern periodic table are arranged in increasing order of their atomic number. In the modern periodic table, the horizontal rows are known as periods and vertical columns are known as groups. There are 7 periods and 18 groups in modern periodic table.

Answer to Problem 3.29E

The name of an element that contains a half-filled 5s electron is rubidium and its symbol is Rb respectively.

Explanation of Solution

Electronic configuration tells about the arrangement of the electrons in each subshell and orbit of an atom.

The electronic configuration for an element that contains a half-filled 5s electron would be 1s22s22p63s23p64s23d104p65s1. Thus, the total number of electrons is 37. The number of electrons corresponds to the atomic number of an element. Therefore, the atomic number of an element is 37 that is rubidium. The symbol used for rubidium is Rb

Conclusion

The name of an element that contains a half-filled 5s electron is rubidium and its symbol is Rb respectively.

Interpretation Introduction

(c)

Interpretation:

The symbol and name for an element that contains half-filled 6p electrons is to be predicted.

Concept introduction:

The elements in a modern periodic table are arranged in increasing order of their atomic number. In the modern periodic table, the horizontal rows are known as periods and vertical columns are known as groups. There are 7 periods and 18 groups in modern periodic table.

Answer to Problem 3.29E

The name of an element that contains half-filled 6p electrons is bismuth and its symbol is Bi respectively.

Explanation of Solution

Electronic configuration tells about the arrangement of the electrons in each subshell and orbit of an atom.

The electronic configuration for an element that contains a half-filled 6p electrons would be 1s22s22p63s23p64s23d104p65s24d105p66s24f145d106p3. The 4s and 5s orbitals are filled first because the energy of 4s and 5s orbital is lower than the 3d and 4d. Thus, the total number of electrons is 83. The number of electrons corresponds to the atomic number of an element. Therefore, the atomic number of an element is 83 that is bismuth. The symbol used for bismuth is Bi.

Conclusion

The name of an element that contains half-filled 6p electrons is bismuth and its symbol is Bi respectively.

Interpretation Introduction

(d)

Interpretation:

The symbol and name for an element in which last electron completes the 4d subshell is to be predicted.

Concept introduction:

The elements in a modern periodic table are arranged in increasing order of their atomic number. In the modern periodic table, the horizontal rows are known as periods and vertical columns are known as groups. There are 7 periods and 18 groups in modern periodic table.

Answer to Problem 3.29E

The name of an element in which the last electron completes the 4d subshell is palladium and its symbol is Pd respectively.

Explanation of Solution

Electronic configuration tells about the arrangement of the electrons in each subshell and orbit of an atom.

The electronic configuration for an element in which the last electron completes the 4d subshell would be 1s22s22p63s23p64s23d104p65s24d10. The 4s and 5s orbitals are filled first because the energy of 4s and 5s orbital is lower than the 3d and 4d. Thus, the total number of electrons is 46. The number of electrons corresponds to the atomic number of an element. Therefore, the atomic number of an element is 46 that is palladium. The symbol used for palladium is Pd.

Conclusion

The name of an element in which the last electron completes the 4d subshell is palladium and its symbol is Pd respectively.

Interpretation Introduction

(e)

Interpretation:

The symbol and name for the element in which the last electron half fills the 4f subshell is to be predicted.

Concept introduction:

The elements in a modern periodic table are arranged in increasing order of their atomic number. In the modern periodic table, the horizontal rows are known as periods and vertical columns are known as groups. There are 7 periods and 18 groups in modern periodic table.

Answer to Problem 3.29E

The name of an element in which the last electron half fills the 4f subshell is europium. The symbol used for europium is Eu.

Explanation of Solution

Electronic configuration tells about the arrangement of the electrons in each subshell and orbit of an atom.

The electronic configuration for an element in which the last electron half fills the 4f subshell would be 1s22s22p63s23p64s23d104p65s24d105p66s24f7. The 4s and 5s orbitals are filled first because the energy of 4s and 5s orbital is lower than the 3d and 4d. Thus, the total number of electrons is 63. The number of electrons corresponds to the atomic number of an element. Therefore, the atomic number of an element is 63 that is palladium. The symbol used for europium is Eu.

Conclusion

The name of an element in which the last electron half fills the 4f subshell is europium. The symbol used for europium is Eu.
