Naming Covalent Compounds Practice Worksheet

Naming Covalent Compounds Practice Worksheet – Naming compounds is an important concept in chemical science. It is about assigning a specific name to an chemical compound, based on its composition. When you name a compound is a crucial indicator of the properties and structure of the compound. There are several kinds of chemical compounds. They include chemical compounds that are ionic, covalent, and binary compounds.

Naming Ionic Compounds

Ionic compounds arise from an exchange of electrons among atoms. They consist with positively charged, cations and negatively charged anion. The guidelines for naming ionic compounds are as below:

1. Write the name of cation first, followed by it’s anion’s name.
2. If the cation contains more than one possible charge, indicate the charge using Roman numerals inside parentheses.
3. In the case of a multiatomic ion, select the name of the anion.

Examples:

• NaCl is a common name for sodium chloride.
• FeCl3 is known as iron(III) chloride.
• Mg(NO3)2 is known as magnesium nitrate.

Naming Covalent Compounds

They are created by the exchange of electrons between atoms. They are made up of molecules composed consisting of two or even more atoms. The guidelines for naming covalent compounds are as in the following order:

1. Enter the name of the first element of the formula.
2. Enter the name of the second element in the formula, changing the ending“-ide” to “-ide”.
3. Prefixes are used to indicate the quantity of atoms contained in each element in the molecule. The exception is“mono-,” the particular prefix “mono-” for the first element.

Examples:

• CO2 is named carbon dioxide.
• N2O is named dinitrogen monoxide.
• The term SF6 stands for sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are substances made of two components. The rules for naming binary compounds are as according to:

1. Write the name of the first element of the formula.
2. Write“name” of second component in the formula, changing the end in the form of “-ide”.

Examples:

• Hydrogen chloride is the name given to it.
• CO is a chemical compound known as carbon monoxide.
• CaO is named calcium oxide.

Practice Exercises

To aid in learning in the classroom, the worksheet contains training exercises to help students name ionic compound, compounds with covalent bonds, or binary substances. These exercises will allow students to build a solid understanding of the principles for naming chemical compounds.

Ionic Compound Naming Exercises:

1. Na2S
2. KBr
3. CaF2
4. Al2O3

Covalent Compound Naming Exercises:

1. CO
2. SO2
3. N2O4
4. H2O2

Binary Compound Naming Exercises:

1. Cl2O7
2. P2S5
3. BrF3
4. NO

After completing these tasks, students will have confidence making chemical compounds known and be able apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an important concept in chemistry that requires a good understanding of the rules and guidelines for names for different kinds of compounds. Following the guidelines outlined in this worksheet and experimenting with the included activities, students will be able comfortably identify covalent, ionic, and binary compounds. This knowledge is essential for the success of chemistry and provides solid foundations for further studies in the area.
