Naming Covalent Molecular Compounds Worksheet

Naming Covalent Molecular Compounds Worksheet – Naming chemical compounds is an essential concept in chemical science. It is the process of assigning a distinct name to the chemical compound on the basis of its composition. A name for a compound gives important information about its properties and structure. There are different types of chemical compounds. They include organic compounds, covalent ones along with binary and covalent compounds.

Naming Ionic Compounds

The Ionic compound is formed by an exchange of electrons among atoms. They consist of positively charged cations and negatively charged anions. The rules for naming Ionic compounds are as they are:

1. Note the name of the cation first, followed by the name of the anion.
2. If the cation may have multiple possible charges mark the charge in Roman numerals enclosed in parentheses.
3. If an anion’s structure is polyatomic ion, select the name of the anion.

Examples:

• NaCl is a synonym for sodium chloride.
• FeCl3 is named iron(III) chloride.
• Mg(NO3)2 is also known as magnesium-nitrate.

Naming Covalent Compounds

Covalent compounds are created through the sharing of electrons between atoms. They consist of molecules made by two or more atoms. The rules for naming compounds that are covalent are as they are:

1. Name the first element of the formula.
2. Enter“name” of second component of the formula, and change the ending in the form of “-ide”.
3. Use prefixes to indicate the number of elements in every element of the molecule, except for“mono-” which indicates the number of atoms in the molecule “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 substances made of two components. The rules for choosing the proper name for binary compounds is as follows:

1. Enter the name of the first element of the formula.
2. Write“I” as the title of your second ingredient of the formula, and change the end“-ide. “-ide”.

Examples:

• It is known as hydrogen chloride.
• CO is a synonym for carbon monoxide.
• CaO is a name for calcium oxide.

Practice Exercises

In order to reinforce the learning process this worksheet will offer practices for naming ionic molecules, covalent compound, in addition to binary compounds. This will help students establish a firm 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

By finishing these exercises students will become more confident in being able to identify chemical compounds and be able to apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an essential concept in chemistry that requires a clear understanding of the rules and guidelines for names for different kinds of compounds. By following the rules outlined in this worksheet and practicing through the exercises provided, students are able to easily identify ionic, covalent the binary chemical compounds. This skill is essential to successful chemistry, and it will lay an excellent foundation for future research in the field.
