Chapter 6, Problem 35A

Interpretation Introduction

Interpretation:

The Nobel gas which does not have eight electrons in its highest occupied energy level is to be identified.

Concept Introduction :

The elements can be classified into four classes: s-block, p-block, d-block, and f-block, based on which subshell the last electron entered, the elements are sorted.The s-block includes 1A, 2A, and helium. The p-block includes 3A, 4A, 5A, 6A, 7A, and 8A. The d-block includes transition elements, and the f-block includes inner transition elements.

Answer to Problem 35A

Option a

Explanation of Solution

In the transition elements, the last electron entersthe d-block and has partially filled the d-subshell.

So, silver, iron, and zirconium belong to the d-block as they have partially filled the d-subshell. d-block elements are called transition elements.

Aluminum is a p-block element.

Thus, the correct option is a.
