Introduction
In chemistry, the naming of compounds is a crucial aspect of understanding their composition and properties. The suffixes used in the names of compounds provide valuable information about the type of compound and its composition. In this article, we will explore the names of the compounds $FeS$, $NaCl$, and $Al_2O_3$ and determine the suffix that they all end in.
Understanding the Suffixes
The suffixes used in the names of compounds are:
- -ite: This suffix is used for compounds that contain a metal and a nonmetal, where the metal is in a +2 oxidation state.
- -ide: This suffix is used for compounds that contain a metal and a nonmetal, where the metal is in a -1 oxidation state.
- -ate: This suffix is used for compounds that contain a metal and a nonmetal, where the metal is in a +1 oxidation state.
- -ic: This suffix is used for compounds that contain a metal and a nonmetal, where the metal is in a +3 oxidation state.
Analyzing the Compounds
FeS
The compound $FeS$ is composed of iron (Fe) and sulfur (S). Iron is a metal that can exist in different oxidation states, including +2 and +3. In the compound $FeS$, iron is in a +2 oxidation state. Since the metal is in a +2 oxidation state, the suffix used in the name of the compound is -ite.
NaCl
The compound $NaCl$ is composed of sodium (Na) and chlorine (Cl). Sodium is a metal that can exist in different oxidation states, including +1. In the compound $NaCl$, sodium is in a +1 oxidation state. However, since the metal is in a +1 oxidation state, the suffix used in the name of the compound is -ide.
Al2O3
The compound $Al_2O_3$ is composed of aluminum (Al) and oxygen (O). Aluminum is a metal that can exist in different oxidation states, including +3. In the compound $Al_2O_3$, aluminum is in a +3 oxidation state. Since the metal is in a +3 oxidation state, the suffix used in the name of the compound is -ic.
Conclusion
In conclusion, the names of the compounds $FeS$, $NaCl$, and $Al_2O_3$ all end in the suffix -ite, -ide, and -ic respectively. The suffixes used in the names of compounds provide valuable information about the type of compound and its composition. Understanding the suffixes used in the names of compounds is essential for chemists and scientists to accurately identify and describe the properties of compounds.
Key Takeaways
- The suffix -ite is used for compounds that contain a metal and a nonmetal, where the metal is in a +2 oxidation state.

Q: What is the significance of the suffixes used in the names of compounds?
A: The suffixes used in the names of compounds provide valuable information about the type of compound and its composition.
Q: What is the difference between the suffixes -ite, -ide, -ate, and -ic?
A: The suffixes -ite, -ide, -ate, and -ic are used to indicate the oxidation state of the metal in a compound. The suffix -ite is used for compounds that contain a metal and a nonmetal, where the metal is in a +2 oxidation state. The suffix -ide is used for compounds that contain a metal and a nonmetal, where the metal is in a -1 oxidation state. The suffix -ate is used for compounds that contain a metal and a nonmetal, where the metal is in a +1 oxidation state. The suffix -ic is used for compounds that contain a metal and a nonmetal, where the metal is in a +3 oxidation state.
Q: How do I determine the suffix used in the name of a compound?
A: To determine the suffix used in the name of a compound, you need to identify the metal and the nonmetal in the compound and determine the oxidation state of the metal. Once you have determined the oxidation state of the metal, you can use the following table to determine the suffix used in the name of the compound:
| Oxidation State | Suffix |
|---|---|
| +2 | -ite |
| -1 | -ide |
| +1 | -ate |
| +3 | -ic |
