Naming Writing Compounds Worksheet

Naming Writing Compounds Worksheet – Naming of compounds is a fundamental idea in chemistry. It involves assigning an unique name to the chemical compound on the basis of its composition. In addition, the name assigned to the chemical compound is a crucial indicator of the properties and structure of the compound. There are a variety of chemical compounds, including organic compounds, covalent ones, or binary substances.

Naming Ionic Compounds

Ionic compounds are created by transfers of electrons across atoms. They consist of positively charged cations and negatively charged anion. The rules of naming ionic compounds are as below:

1. Enter the name of the cation first, followed by your name and the name of the anion.
2. If the cation is charged with more than one possible charge Indicate the charge with Roman numerals in parentheses.
3. For anion that is not a polyatomic ion, you should use the name given to the anion.

Examples:

• NaCl is also known as sodium chloride.
• FeCl3 is known as iron(III) chloride.
• Mg(NO3)2 is also known as magnesium nitrate.

Naming Covalent Compounds

The formation of covalent compounds is caused by the exchange of electrons between atoms. They consist of molecules made up of two or more atoms. The rules for naming compounds that are covalent are as according to:

1. Note the name of first element in the formula.
2. Write“Element 2” as the title in the formula, changing the ending“ide “-ide”.
3. Prefixes can be used to indicate the number of atoms for each element in the molecule. This is not the case for the prefix “mono-” for the first element.

Examples:

• CO2 is named carbon dioxide.
• N2O is named dinitrogen monoxide.
• So, SF6 is a sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are substances made by two elements. The rules for names of binary compounds can be described as they are:

1. Enter the name of the first element in the formula.
2. Write“Name” for second element in the formula, and change the ending in the form of “-ide”.

Examples:

• Hydrogen chloride is also known as hydrogen.
• CO is the abbreviation for carbon monoxide.
• CaO is the name given to calcium oxide.

Practice Exercises

To strengthen the understanding for students, the worksheets will include activities for practicing naming ionic molecules, covalent compound, also known as binary compounds. These exercises can help students build a solid understanding of the rules 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

Through these exercises, learners will become confident in understanding chemical compound names and be able to apply these rules to other compounds.

Conclusion:

Naming compounds is an important idea in chemistry that requires an understanding of how to follow the guidelines and rules to calling different kinds of compounds. By adhering to the guidelines set forth in this worksheet and practicing through the exercises provided, students can successfully identify ionic, chemical, or binary compound. This knowledge is vital to being successful in chemistry. It provides a strong foundation for further research in the area.
