Chapter 12, Problem 7E

Interpretation Introduction

Interpretation:

The transfer of electrons from aluminum atoms to oxygen atoms that accounts for the chemical formula of the compound ${\text{Al}}_{\text{2}}{\text{O}}_{\text{3}}$ is to be sketched.

Concept introduction:

Ionic compounds are made up of ions held together at a fixed position. Many elements occur naturally in the form of ionic compounds. Ionic compounds are formed by transfer of electrons from the less electronegative element to the more electronegative element.
