Chapter 6, Problem 46A

Interpretation Introduction

Interpretation:

The position in the periodic table needs to be determined using the atom’s valence electron configuration.

Concept introduction:

Electronic configuration of an element is the arrangement of elements in different orbitals like s, p, d, f. The filing of the electrons in the orbitals follow the Aufbau Principle.

Answer to Problem 46A

The location of an element on the periodic table can be determined by the number of valence electrons in an atom.

Explanation of Solution

The location of an element on the periodic table with respect to its group member can be determined by the number of valence electrons in an atom. Group 1 has one valence electron; Group 2 has two valence electrons. Similarly, Group 13 has three and Group 18 has eight valence electrons.

Conclusion

The number of valence electrons in an atom helps in predicting the location of an element on the periodic table.
