Chapter 8, Problem 8.44P

(a)

Interpretation Introduction

Interpretation:

The element and its condensed ground state electronic configuration with excited state electronic configuration 1s22s22p63s13p1 are to be identified.

Concept introduction:

The electronic configuration tells about the distribution of electrons in various atomic orbital. The condensed electronic configuration is a way to write the electronic configuration where the inner shell configurations are compressed to the nearest noble gas configuration and only the valence shell configuration is written in the expanded form.

The lower stable energy level is known as the ground state whereas the higher unstable energy level is called the excited state. Elements in the excited state have much tendency to lose energy and come back to the ground state.

Answer to Problem 8.44P

The element with the excited state electronic configuration 1s22s22p63s13p1 is magnesium and its condensed ground state electronic configuration is [Ne]3s2.

Explanation of Solution

The excited state electronic configuration of the given element is 1s22s22p63s13p1. This indicates the element belongs to the 3rd period of the periodic table. The excited 3p electron returns to the 3s orbital with the release of energy. So the element of the 3rd period that has two electrons in the 3s orbital is magnesium (Mg;Z=12) and its condensed ground state electronic configuration is [Ne]3s2.

Conclusion

The given element is magnesium and its condensed ground state electronic configuration is [Ne]3s2.

(b)

Interpretation Introduction

Interpretation:

The element and its condensed ground state electronic configuration with excited state electronic configuration 1s22s22p63s23p44s1 are to be identified.

Concept introduction:

The electronic configuration tells about the distribution of electrons in various atomic orbital. The condensed electronic configuration is a way to write the electronic configuration where the inner shell configurations are compressed to the nearest noble gas configuration and only the valence shell configuration is written in the expanded form.

The lower stable energy level is known as the ground state whereas the higher unstable energy level is called the excited state. Elements in the excited state have much tendency to lose energy and come back to the ground state.

Answer to Problem 8.44P

The element with the excited state electronic configuration 1s22s22p63s23p44s1 is chlorine and its condensed ground state electronic configuration is [Ne]3s23p5.

Explanation of Solution

The excited state electronic configuration of the given element is 1s22s22p63s23p44s1. This indicates the element belongs to the 3rd period of the periodic table. The excited 4s electron returns to the 3p orbital with the release of energy. So the element of the 3rd period that has five electrons in the 3p orbital is chlorine and its condensed ground state electronic configuration is [Ne]3s23p5.

Conclusion

The given element is chlorine and its condensed ground state electronic configuration is [Ne]3s23p5.

(c)

Interpretation Introduction

Interpretation:

The element and its condensed ground state electronic configuration with excited state electronic configuration 1s22s22p63s23p64s23d44p1 are to be identified.

Concept introduction:

The electronic configuration tells about the distribution of electrons in various atomic orbital. The condensed electronic configuration is a way to write the electronic configuration where the inner shell configurations are compressed to the nearest noble gas configuration and only the valence shell configuration is written in the expanded form.

The lower stable energy level is known as the ground state whereas the higher unstable energy level is called the excited state. Elements in the excited state have much tendency to lose energy and come back to the ground state.

Answer to Problem 8.44P

The element with the excited state electronic configuration 1s22s22p63s23p64s23d44p1 is manganese and its condensed ground state electronic configuration is [Ar]4s23d5.

Explanation of Solution

The excited state electronic configuration of the given element is 1s22s22p63s23p64s23d44p1. This indicates the element belongs to the 4th period of the periodic table. The excited 4p electron returns to the 3d orbital with the release of energy. So the element of the 4th period that has five electrons in the 3d orbital is manganese and its condensed ground state electronic configuration is [Ar]4s23d5.

Conclusion

The given element is manganese and its condensed ground state electronic configuration is [Ar]4s23d5.

Interpretation Introduction

Interpretation:

The element and its condensed ground state electronic configuration with excited state electronic configuration 1s22s22p53s1 are to be identified.

Concept introduction:

The electronic configuration tells about the distribution of electrons in various atomic orbital. The condensed electronic configuration is a way to write the electronic configuration where the inner shell configurations are compressed to the nearest noble gas configuration and only the valence shell configuration is written in the expanded form.

The lower stable energy level is known as the ground state whereas the higher unstable energy level is called the excited state. Elements in the excited state have much tendency to lose energy and come back to the ground state.

Answer to Problem 8.44P

The element with the excited state electronic configuration 1s22s22p53s1 is neon and its condensed ground state electronic configuration is [He]2s22p6.

Explanation of Solution

The excited state electronic configuration of the given element is 1s22s22p53s1. This indicates the element belongs to the 2nd period of the periodic table. The excited 3s electron returns to the 2p orbital with the release of energy. So the element of the 2nd period that has six electrons in the 2p orbital is neon and its condensed ground state electronic configuration is [He]2s22p6.

Conclusion

The given element is neon and its condensed ground state electronic configuration is [He]2s22p6.
