Chapter 8, Problem 13RQ

Interpretation Introduction

Interpretation:

The reason that the Lewis symbol for an atom only considers the electrons in its valence shell is to be explained.

Concept Introduction:

A Lewis symbol is a chemical symbol surrounded by dots that, indicates the number of electrons on the valence shell of an atom.

The elements that belong to the same group have the same number of electrons in their Lewis symbol.

The octet rule is a chemical rule that states that every atom has a tendency to gain or lose electrons in order to achieve noble gas electronic configuration in their outer or valence shell.
