Chapter 3, Problem 3.83AP

a.

Summary Introduction

To determine:

The compound ${\text{CBr}}_{\text{4}}$ as ionic or covalent and the correct name of the compound.

Concept introduction:

Ionic compounds are made up of ions that are bonded by electrostatic forces of attraction. In ionic compounds, cations are defined as the positively charged ions, whereas anions are the negatively charged ions. They are made up of metal and nonmetal elements.

Covalent compounds are defined as the molecules which have strong bonds because the atom from which the covalent molecules are made are held very tightly together. The attractions between the individual molecules in covalent compounds are small.

These are the molecules made mainly of non-metals by sharing electrons and held together by Vander Waal forces.

A chemical formula represents the number of atoms of each element present in a molecule of a compound.
