Section 6.3 Naming Compounds And Writing Formulas Worksheet Answer Key – Naming compounds is a fundamental concept in chemistry. It is the process of assigning a distinct name to an chemical compound, based on its composition. What is the title of a chemical compound will provide crucial information about the properties and structure of the compound. There are various kinds of chemical compounds, such as those with ionic properties, covalent compound, the binary type of compounds.
Naming Ionic Compounds
Ionic compounds arise from electron transfer amongst atoms. They are made up mostly of positively charged electrons as well as negatively charged anion. The rules for naming Ionic compounds are as like this:
- Write the name for the initial cation, followed by its name.
- If the cation may have more than one charge identify the charge by using Roman numbers enclosed in parentheses.
- For anion that is not a polyatomic ion make use of the name for the anion.
Examples:
- NaCl is the name given to sodium chloride.
- FeCl3 is named iron(III) chloride.
- Mg(NO3)2 is known as magnesium nitrate.
Naming Covalent Compounds
Covalent compounds are created through the exchange of electrons between atoms. They consist of molecules made by two or more atoms. The guidelines for naming covalent compounds are as according to:
- Name the first element in the formula.
- Enter“Element 2” as the title in the formula, and change the end“ide “-ide”.
- Prefixes are used to indicate the amount of atoms that make up every element of the molecule. Except for using the suffix “mono-” for the first element.
Examples:
- CO2 is a carbon dioxide derived name.
- N2O is named dinitrogen monoxide.
- So, SF6 is a sulfur hexafluoride.
Naming Binary Compounds
Binary compounds are those made of two components. The rules for calling binary compounds are as below:
- Inscribe the name of the first element of the formula.
- Enter the name of the second element of the formula, and change the ending“-ide “-ide”.
Examples:
- The term hydrogen chloride refers to the HCl.
- CO is a synonym for carbon monoxide.
- CaO is the name given to calcium oxide.
Practice Exercises
To further reinforce the learning for students, the worksheets will include examples of how to name ionic elements, covalent components, as well as binary compound. These exercises will allow students to establish a firm understanding of the rules used to name chemical compounds.
Ionic Compound Naming Exercises:
- Na2S
- KBr
- CaF2
- Al2O3
Covalent Compound Naming Exercises:
- CO
- SO2
- N2O4
- H2O2
Binary Compound Naming Exercises:

As they complete these exercises students will develop confidence in naming chemical compounds and will be able apply the rules to other chemical compounds.
Conclusion:
Naming compounds is an essential concept in chemistry , and demands a firm understanding these rules as well as guidelines for naming different types of compounds. In following the principles laid out in this worksheet and experimenting using the provided exercises, students will be able to comfortably identify covalent, ionic and other binary chemicals. This information is crucial to being successful in chemistry. It provides the foundation for future studies in the field.
