Chapter 4, Problem 4.77EP

Interpretation Introduction

Interpretation:

Incorrect characterisation of ${\text{OF}}_{\text{2}}$ as an ionic compound containing ${\text{O}}^{\text{2-}}$ and ${\text{F}}^{\text{-}}$ ions has to be explained.

Concept Introduction:

Ionic solids or ionic crystals are formed due to the transfer of electrons from one atom to another.  Both positive and negative charge atoms are held together by attractive forces.

An ionic compound in solid state consists of positive and negative charges.  These positive and negative charges of ions are alternatively arranged.  The opposite charged ions are held together by attractive forces.
