Rules For Naming Chemical Compounds Worksheet

Rules For Naming Chemical Compounds Worksheet – Naming of compounds is a fundamental concept in chemical science. It involves assigning an unique name to one chemical substance based on its composition. An individual’s name on a chemical compound gives important information about its properties and structure. There are different kinds of chemical compounds. This includes covalent compounds, ionic compounds, also known as binary compounds.

Naming Ionic Compounds

Ionic compounds are created by electron transfer from atoms. They are made up comprise positively charged Cations as well as negatively charged anion. The rules to name ionic compounds are as the following:

1. Note the name of the compound first, and then your name and the name of the anion.
2. If the cation is charged with multiple possible charges mark the charge in Roman numbers enclosed in parentheses.
3. If there is a possibility of polyatomic ion make use of the name for the ion.

Examples:

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

Naming Covalent Compounds

Covalent compounds form through sharing electrons among atoms. They consist of molecules made by two or many atoms. The rules for naming covalent compounds are as the following:

1. Write the name for the first element in the formula.
2. Write an appropriate name for each element of the formula, and change the ending“-ide. “-ide”.
3. Use prefixes to indicate the number of atoms in each element in the molecule, with using the suffix “mono-” for the first element.

Examples:

• CO2 is also known as carbon dioxide.
• N2O is named dinitrogen monoxide.
• SF6 is named sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are the ones made of two components. The rules for names for binary compounds are as like:

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

Examples:

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

Practice Exercises

To help reinforce learning in the classroom, the worksheet contains practice exercises for naming ionic components, covalent compounds, including binary ones. These exercises will help students get a better understanding of what rules are used 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

When they complete these activities, students will have confidence formulating chemical names and be able apply the rules to other compounds.

Conclusion:

Naming compounds is an essential idea in chemistry that requires an understanding of these rules as well as guidelines to calling different kinds of compounds. Through following the steps laid out in this worksheet and practicing with the included activities, students are able to easily identify ionic, covalent or binary compound. This is a must for achievement in chemistry. It will also provide the foundation for future studies in the area.
