Chapter 2, Problem 2.79QP

(a)

Interpretation Introduction

Interpretation: The given compounds are ${\text{Mg}}_3\text{N}$, $\text{Mg}{\left({\text{NO}}_2\right)}_2$, $\text{Mg}{\left({\text{NO}}_3\right)}_2$, and $\text{Mg}{\left(\text{NO}\right)}_2$. The compound which is magnesium nitrite is to be determined.

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. The group $2$ elements, in the periodic table, show the presence of two electrons in their outermost shell. Ions which comprise of at least one or more than one atom are known as polyatomic ions. The systematic name to the chemical compounds is given by nomenclature rule.

To determine: If the chemical name of ${\text{Mg}}_3\text{N}$ is magnesium nitrite.

(b)

(d)

Interpretation Introduction

To determine: The chemical name of $\text{Mg}{\left(\text{NO}\right)}_2$ is magnesium nitrite.
