Answer to Problem 3.31E

The abbreviated electronic configuration for an element that contains 24 electrons is [Ar]4s13d5 respectively.

Explanation of Solution

Electronic configuration tells about the arrangement of the electrons in each subshell and each orbit of an atom. The abbreviated electronic configuration is the simplified representation of electrons in the valence shell by using noble gas symbols. This form is also known as noble gas configuration.

The element contains 24 electrons. Thus, the atomic number of an element is 24 that is chromium. The electronic configuration of chromium is 1s22s22p63s23p64s13d5. The number of electrons present in the inner shells of chromium that is 1s22s22p63s23p6 represents the electronic configuration of argon. Therefore, the symbol of argon [Ar] is used to represent the number of electrons present in the inner shells of chromium. Hence, the abbreviated electronic configuration for chromium is [Ar]4s13d5.

Conclusion

The abbreviated electronic configuration for an element that contains 24 electrons is [Ar]4s13d5 respectively.

Interpretation Introduction

(b)

Interpretation:

The abbreviated electronic configuration for an element number 21 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 3.31E

The abbreviated electronic configuration for an element number 21 is [Ar]4s23d1 respectively.

Explanation of Solution

Electronic configuration tells about the arrangement of the electrons in each subshell and each orbit of an atom. The abbreviated electronic configuration is the simplified representation of electrons in the valence shell by using noble gas symbols. This form is also known as noble gas configuration.

The atomic number of an element is 21 that is scandium. The electronic configuration of scandium is 1s22s22p63s23p64s23d1. The number of electrons present in the inner shells of scandium that is 1s22s22p63s23p6 represents the electronic configuration of argon. Therefore, the symbol of argon [Ar] is used to represent the number of electrons present in the inner shells of scandium. Hence, the abbreviated electronic configuration for scandium is [Ar]4s23d1.

Conclusion

The abbreviated electronic configuration for an element number 21 is [Ar]4s23d1 respectively.

Answer to Problem 3.31E

The abbreviated electronic configuration for iodine is [Kr]5s24d105p5 respectively.

Explanation of Solution

Electronic configuration tells about the arrangement of the electrons in each subshell and each orbit of an atom. The abbreviated electronic configuration is the simplified representation of electrons in the valence shell by using noble gas symbols. This form is also known as noble gas configuration.

The atomic number of iodine is 53. The electronic configuration of iodine is 1s22s22p63s23p64s23d104p65s24d105p5. The number of electrons present in the inner shells of iodine that is 1s22s22p63s23p64s23d104p6 represents the electronic configuration of krypton. Therefore, the symbol of krypton [Kr] is used to represent the number of electrons present in the inner shells of iodine. Hence, the abbreviated electronic configuration for iodine is [Kr]5s24d105p5.

Conclusion

The abbreviated electronic configuration for iodine is [Kr]5s24d105p5 respectively.

Answer to Problem 3.31E

The abbreviated electronic configuration for copper is [Ar]4s13d10 respectively.

Explanation of Solution

Electronic configuration tells about the arrangement of the electrons in each subshell and each orbit of an atom. The abbreviated electronic configuration is the simplified representation of electrons in the valence shell by using noble gas symbols. This form is also known as noble gas configuration.

The atomic number of copper is 29. The electronic configuration of copper is 1s22s22p63s23p64s13d10. The number of electrons present in the inner shells of copper that is 1s22s22p63s23p6 represents the electronic configuration of argon. Therefore, the symbol of argon [Ar] is used to represent the number of electrons present in the inner shells of copper. Hence, the abbreviated electronic configuration for copper is [Ar]4s13d10.

Conclusion

The abbreviated electronic configuration for copper is [Ar]4s13d10 respectively.
