Name each compound:

a .  NaF b .  gCl 2 c .  Li 2 O d .  A1 2 O 3 e .  CaCO 3

Interpretation Introduction

Interpretation:

Each compound is to be named.

Concept introduction:

Molecular compounds contain only nonmetals, which are covalently bonded to each other.

While naming molecular compounds, the name of the first element is written first, followed by the name of the second element and then, by a suffix “ide”.

Ionic compounds are named by writing the name of the cation (metal), followed by the name of the anion (nonmetal) and then, by a suffix “ide”.

While naming ionic compounds, prefixes, such as, di or tri, are not used to indicate the number of atoms.

Explanation of Solution

a) NaF

NaF, sodium fluoride, is an ionic compound that consists of metal and nonmetal elements bonded together via an ionic bond, which is formed as a result of electron transfer between the ions.

Here, the metal acts as cation (Na+) and the nonmetal act as anion (F).

Ionic compounds are named by writing the name of the cation (metal), followed by the name of the anion (non-metal) and then, by a suffix “ide”.

Therefore, the name of the given compound is sodium fluoride.

b) MgCl2

MgCl2, magnesium chloride, is an ionic compound that consists of metal and nonmetal elements bonded together via ionic bonds, which are formed as a result of electron transfer between the ions.

Here, the metal act as cation (Mg+) and the nonmetal acts as anion (Cl).

Ionic compounds are named by writing the name of the cation (metal), followed by the name of the anion (non-metal) and then, by a suffix “ide”.

Therefore, the name of the given compound is magnesium chloride.

c) Li2O

Li2O, lithium oxide, is an ionic compound that consists of metal and nonmetal elements bonded together via ionic bonds, which are formed as a result of electron transfer between the ions.

Here, the metal acts as cation (Li2+) and the nonmetal acts as anion (O2)
