Chapter 9.2, Problem 22LC

Interpretation Introduction

Interpretation: The conditions that are met while writing the formula of an ionic compound are to be stated.

Concept Introduction : Ionic compounds are formed by the transfer of electrons between metal and non-metal. They are named as $\text{Name}\text{of}\text{metal}+\text{Stem}\text{of}\text{non-metal}+\text{'}ide\text{'}$

Answer to Problem 22LC

The charge must be balanced while writing the formula of the ionic compound.

Explanation of Solution

The charge must be balanced while writing the formula of the ionic compound.

For example, beryllium chloride is composed of ${\text{Be}}^{2+}$ and ${\text{Cl}}^{-}$ . By the criss-cross method, the chemical formula of the compound is ${\text{BeCl}}_2$ (+2 charge on Be is balanced by 2 anions of Cl).
