Understanding Writing Formulas: Writing Formulas And Naming Compounds Worksheet

Chemical formulas represent the composition of chemical compounds using symbols for the elements and numbers to indicate the proportions of atoms or molecules.

There are three main types of chemical formulas:

• Molecular formulas: Show the actual number and types of atoms in a molecule.
• Empirical formulas: Give the simplest whole-number ratio of atoms in a compound.
• Structural formulas: Show the arrangement of atoms within a molecule.

The rules for writing chemical formulas include:

• Use the element symbol for each element.
• Indicate the number of atoms of each element using subscripts.
• Group elements in the order: metal, nonmetal, hydrogen, and then oxygen.

Naming Compounds

The rules for naming ionic compounds depend on the charges of the ions involved.

• For a metal and a nonmetal, the metal name is followed by the nonmetal name with the suffix -ide.
• For a metal with multiple charges, the charge is indicated using Roman numerals in parentheses.

The rules for naming covalent compounds are more complex and depend on the number of atoms of each element and the presence of functional groups.

• For two nonmetals, the prefixes mono-, di-, tri-, tetra-, etc. are used to indicate the number of atoms of each element.
• For compounds with functional groups, the name of the functional group is used as a suffix.

Worksheet Activities

Worksheet exercises can help students practice writing formulas and naming compounds.

• Exercises on writing formulas can include tasks such as writing the formula for a given compound name or determining the formula from a given chemical equation.
• Exercises on naming compounds can include tasks such as naming a given compound formula or writing the formula for a given compound name.

Assessment, Writing formulas and naming compounds worksheet

A rubric can be used to assess student work on the worksheets.

• The rubric can include criteria such as accuracy, completeness, and clarity.
• The rubric can be used to provide feedback to students and to identify areas where they need additional support.

FAQ Guide

What is the purpose of a chemical formula?

A chemical formula provides a concise representation of the elemental composition and structure of a compound, indicating the types and proportions of atoms present.

How do I name an ionic compound?

Ionic compounds are named using the cation (positive ion) first, followed by the anion (negative ion). The name of the cation typically ends in “-ium,” while the name of the anion ends in “-ide.”

What are the rules for writing a balanced chemical equation?

A balanced chemical equation ensures that the number of atoms of each element is the same on both sides of the equation. This is achieved by adjusting the stoichiometric coefficients in front of each chemical formula.
