Chapter 8, Problem 8.77P

(a)

Interpretation Introduction

Interpretation:

The charge and full ground state electron configuration of the ion likely to be formed by Al is to be determined.

Concept introduction:

The electronic configuration of an atom describes how the electrons are ditributed in its atom among various shells and subshells. It is used to predict the chemical, physical, electrical and magnetic properties of the substance. The full electronic configuration of an atom tells about the distribution of electrons in the various atomic orbitals.

Answer to Problem 8.77P

The charge of monoatomic ion likely to be formed by Al atom is +3.

The full ground state electron configuration of the ion likely to be formed by Al is 1s22s22p6.

Explanation of Solution

The atomic number of so its ground state electronic configuration is 1s22s22p63s23p1. Its configuration is just three electrons more of the stable noble gas configuration of neon so it loses three electrons to become Al3+ whose full ground state electron configuration is 1s22s22p6.

The ion formation occurs as follows:

Al(1s22s22p63s23p1)3eAl3+(1s22s22p6)

So the charge on the ion formed by Al is +3 and its full ground state electron configuration is 1s22s22p6.

Conclusion

The charge of monoatomic ion likely to be formed by Al atom is +3 and the full ground state electron configuration of the ion likely to be formed by Al is 1s22s22p6.

(b)

Interpretation Introduction

Interpretation:

The charge and full ground state electron configuration of the ion likely to be formed by S is to be determined.

Concept introduction:

The electronic configuration of an atom describes how the electrons are ditributed in its atom among various shells and subshells. It is used to predict the chemical, physical, electrical and magnetic properties of the substance.

Answer to Problem 8.77P

The charge of monoatomic ion likely to be formed by S atom is 2.

The full ground state electron configuration of the ion likely to be formed by S is 1s22s22p63s23p6.

Explanation of Solution

The atomic number of sulphur is 16 so its ground state electronic configuration is 1s22s22p63s23p4. Its configuration is just two electrons short of the stable noble gas configuration of argon so it gains two electrons to become S2 whose full ground state electron configuration is 1s22s22p63s23p6.

The ion formation occurs as follows:

S(1s22s22p63s23p4)+2eS2(1s22s22p63s23p6)

So the charge on the ion formed by S is 2 and its full ground state electron configuration is 1s22s22p63s23p6.

Conclusion

The charge of monoatomic ion likely to be formed by S atom is 2 and the full ground state electron configuration of the ion likely to be formed by S is 1s22s22p63s23p6.

Answer to Problem 8.77P

The charge of monoatomic ion likely to be formed by Sr atom is +2.

The full ground state electron configuration of the ion likely to be formed by Sr is 1s22s22p63s23p64s23d104p6.

Explanation of Solution

The atomic number of strontium is 38 so its ground state electronic configuration is 1s22s22p63s23p64s23d104p65s2. Its configuration is two electrons more of the stable noble gas configuration of krypton so it loses two electrons to become Sr2+ whose full ground state electron configuration is 1s22s22p63s23p64s23d104p6.

The ion formation occurs as follows:

Sr(1s22s22p63s23p64s23d104p65s2)2eSr2+(1s22s22p63s23p64s23d104p6)

So the charge on the ion formed by Sr is +2 and its full ground state electron configuration is 1s22s22p63s23p64s23d104p6.

Conclusion

The charge of monoatomic ion likely to be formed by Sr atom is +2 and the full ground state electron configuration of the ion likely to be formed by Sr is 1s22s22p63s23p64s23d104p6.
