Chapter 2, Problem 124RQ

Interpretation Introduction

Interpretation:

Amongst the following substances, the substances which are binary substances, a triatomic molecule, a diatomic molecule, molecular substances, ionic molecule and in which do we find only electron sharing and only attractions between ions, are to be identified.

${\text{Cl}}_2$, $\text{CaO}$, $\text{HBr}$, ${\text{CuCl}}_2$, ${\text{AsH}}_3$, ${\text{NaNO}}_3$ and ${\text{NO}}_2$

Concept Introduction:

A binary compound is a chemical substance that consists of two elements.

Triatomic molecules are the molecules that are composed of only three atoms. There are homogeneous as well as heterogeneous triatomic molecules.

Electron sharing is the sharing of valence electron between two or more elements.

Diatomic molecules are molecules that are composed of only two atoms. Both the elements may either be same or different, that is, homogeneous and heterogeneous diatomic molecules.

Attraction between ions is the electrostatic attraction between the oppositely charged ions formed from the elements after losing or gaining one or two pairs of electrons.

Molecular compounds are compounds that consist of two non-metals atoms.

Ionic compounds are compounds that consist of metal and non-metal atoms.
