Definitions

Ionic compounds are formed when a metal loses one or more electrons to a non-metal. The metal becomes a positively charged ion, called a cation, and the non-metal becomes a negatively charged ion, called an anion. The oppositely charged ions are attracted to each other by electrostatic forces, forming an ionic bond.

The name of an ionic compound is based on the names of the cation and anion. The cation is always named first, followed by the anion. The name of the cation is the same as the name of the metal.

The name of the anion is the root of the non-metal’s name, followed by the suffix -ide.

Exceptions

There are a few exceptions to the rules for naming ionic compounds. For example, the cation of iron(II) is named ferrous, and the cation of iron(III) is named ferric. The anion of oxygen is named oxide, and the anion of hydrogen is named hydride.

Naming Rules

Ionic compounds are named based on the names of the ions that compose them. There are general rules for naming both cations and anions.

The name of a cation is the same as the name of the element from which it is formed. For example, the cation formed from sodium is called sodium ion.

The name of an anion is formed by adding the suffix “-ide” to the root of the name of the element from which it is formed. For example, the anion formed from chlorine is called chloride ion.

Naming Cations

When naming cations, the following rules apply:

For cations of metals that form only one type of cation, the name of the cation is the same as the name of the metal. For example, the cation of sodium is called sodium ion.
For cations of metals that form more than one type of cation, the name of the cation includes the Roman numeral of the charge of the cation. For example, the cation of iron(II) is called iron(II) ion, and the cation of iron(III) is called iron(III) ion.

Naming Anions

When naming anions, the following rules apply:

For anions of nonmetals that form only one type of anion, the name of the anion is formed by adding the suffix “-ide” to the root of the name of the nonmetal. For example, the anion of chlorine is called chloride ion.
For anions of nonmetals that form more than one type of anion, the name of the anion includes the suffix “-ide” and the Roman numeral of the charge of the anion. For example, the anion of sulfur(II) is called sulfide ion, and the anion of sulfur(VI) is called sulfate ion.

Practice Problems

To enhance your understanding of ionic compound naming, let’s engage in a series of practice problems.

The following table provides a structured approach to practice naming ionic compounds, including the chemical formula, cation name, anion name, and the corresponding ionic compound name.

Chemical Formula	Cation Name	Anion Name	Ionic Compound Name
NaCl	Sodium	Chloride	Sodium chloride
CaO	Calcium	Oxide	Calcium oxide
Al₂O₃	Aluminum	Oxide	Aluminum oxide
NH₄Cl	Ammonium	Chloride	Ammonium chloride
Fe₂O₃	Iron(III)	Oxide	Iron(III) oxide

4. Examples and Exceptions: Naming Of Ionic Compounds Worksheet

Examples of Correctly Named Ionic Compounds

Correctly named ionic compounds adhere to the naming rules discussed earlier. Here are some examples:

NaCl: Sodium chloride
MgO: Magnesium oxide
CaF ₂: Calcium fluoride
Al ₂O ₃: Aluminum oxide
Fe ₂O ₃: Iron(III) oxide

Exceptions to the Naming Rules

While the naming rules provide a general framework, there are some exceptions to consider:

Ammonium (NH₄⁺): The ammonium ion is named as if it were a metal, despite being a polyatomic ion. In compounds, it is treated as a monovalent cation and named “ammonium.”
Mercury(II):The Roman numeral (II) is used to indicate the +2 oxidation state of mercury in compounds, even though it is not a variable-charge metal.
Iron(II) and Iron(III):Iron can exhibit two common oxidation states (+2 and +3). These are denoted using Roman numerals in the compound name, as in “iron(II) oxide” (FeO) and “iron(III) oxide” (Fe ₂O ₃).
Compounds with Polyatomic Ions:When an ionic compound contains a polyatomic ion, the name of the ion is used as part of the compound name. For example, “sodium sulfate” (Na ₂SO ₄) contains the polyatomic ion sulfate (SO ₄^2-).
