Introduction

Binary ionic compounds are composed of two elements, typically a metal and a nonmetal, that form ions with opposite charges. In this article, we will focus on binary ionic compounds where the central metal atom can form ions with more than one charge. This property is known as variable charge or multiple oxidation states. We will examine the binary ionic compounds CuCl and CuCl₂, and identify the charge on the central metal atom using Roman numerals enclosed in parentheses.

Understanding Variable Charge Metal Atoms

Variable charge metal atoms are capable of forming ions with different charges, depending on the number of electrons they gain or lose. This property is due to the ability of the metal atom to exhibit multiple oxidation states. In the case of copper (Cu), it can form ions with a +1 or +2 charge, depending on the compound it is part of.

Naming Binary Ionic Compounds with Variable Charge Metal Atoms

To name binary ionic compounds with variable charge metal atoms, we need to follow a specific procedure. The name of the compound consists of the name of the metal atom, followed by the name of the nonmetal atom, and the charge on the metal atom enclosed in parentheses.

Example 1: CuCl

In the compound CuCl, the copper atom is in its +1 oxidation state. To name this compound, we write the name of the metal atom, followed by the name of the nonmetal atom, and the charge on the metal atom enclosed in parentheses. Therefore, the name of the compound is copper(I) chloride.

Example 2: CuCl₂

In the compound CuCl₂, the copper atom is in its +2 oxidation state. To name this compound, we write the name of the metal atom, followed by the name of the nonmetal atom, and the charge on the metal atom enclosed in parentheses. Therefore, the name of the compound is copper(II) chloride.

Conclusion

In conclusion, binary ionic compounds with variable charge metal atoms are an important class of compounds that exhibit multiple oxidation states. By following a specific procedure, we can name these compounds using Roman numerals enclosed in parentheses to indicate the charge on the central metal atom. In this article, we have examined the binary ionic compounds CuCl and CuCl₂, and identified the charge on the central metal atom using Roman numerals enclosed in parentheses.
