Engage in a series of exercises designed to test your comprehension, honing your skills in naming and formula writing.

1. Introduction

Ionic compounds are formed by the transfer of electrons between atoms, resulting in positively charged ions (cations) and negatively charged ions (anions). They play a vital role in various chemical processes and are commonly found in nature and industrial applications.

This worksheet aims to reinforce understanding of ionic compound nomenclature and formulas, enabling students to confidently name and write formulas for a range of ionic compounds.

2. Naming Ionic Compounds

Rules for Naming Ionic Compounds

• Name the cation first, followed by the anion.
• For metals with variable charges, use Roman numerals in parentheses to indicate the charge.
• For polyatomic ions, use the suffix “-ate” for anions ending in “-ic” and “-ite” for anions ending in “-ous”.

Examples

• NaCl: sodium chloride
• MgO: magnesium oxide
• Fe ₂O ₃: iron(III) oxide
• Na ₂SO ₄: sodium sulfate
• Ca ₃(PO ₄) ₂: calcium phosphate

3. Writing Ionic Formulas

Principles of Writing Ionic Formulas

• The subscripts in the formula represent the number of atoms or ions of each element required to balance the charges.
• Parentheses are used to group polyatomic ions.
• Brackets are used to indicate the charge of a complex ion.

Examples

• NaCl: sodium chloride
• MgO: magnesium oxide
• Fe ₂O ₃: iron(III) oxide
• Na ₂SO ₄: sodium sulfate
• [Fe(OH) ₆] ^3-: hexahydroxoiron(III) ion
