Chapter 18, Problem 15STP

To determine

To state: several examples of ionic compounds and two properties often shared by these two compounds.

Explanation of Solution

Introduction:

Ionic bonding is the total transmission of valence electron(s) between atoms. It is a type of chemical bond that creates two ions charged in opposite directions. Ionic compounds are stable compounds composed of positively charged cations and negatively charged anions.

Ionic compounds are a combination of metals and non-mental.

Examples of ionic compounds are, $\left(\text{LiCL,NaF,NaCl,NaBr,KCl,}\text{etc}\right)$ and these are metal. An ionic compound that is nonmetal is $\left({\text{MgCl}}_{\text{2}}{\text{,CaCl}}_{\text{2}}{\text{,AlCl}}_{\text{3,}\text{}}\text{}\text{etc}\right)$ .

A metal atom loses an electron and non-metal gains an electron to form an ion resulting in an ionic compound. An ion formed by metal is positively charged and is called a cation. The ion formed by non-metal is negatively charged and is called an anion. Thus, ionic compounds are formed loses and gain of electrons.

Conclusion:

Hence, $\text{LiCL,NaF,NaCl,NaBr,KCl,}{\text{MgCl}}_{\text{2}}{\text{,CaCl}}_{\text{2}}{\text{,AlCl}}_3$ , etc are some examples of ionic compounds.
