Naming Covalent Chemical Compounds Worksheet

Naming Covalent Chemical Compounds Worksheet – Naming compounds is a key concept in chemistry. It is about assigning a specific name to a chemical compound based on its composition. When you name a chemical compound provides crucial information about its properties as well as its structure. There are many types of chemical compounds. They include Ionic compounds, covalent substances, in addition to binary ones.

Naming Ionic Compounds

Ionic compounds are formed by moving electrons around atoms. They are made up comprise positively charged Cations as well as negatively charged anions. The rules to name ionic compounds are as follows:

1. Write the name of the an atom first, followed by that of the anion.
2. If the cation contains more than one possible charge Indicate the charge using Roman numerals in parentheses.
3. If it is a polyatomic ion use the name of the anion.

Examples:

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

Naming Covalent Compounds

Covalent compounds are formed by sharing electrons among atoms. They are composed of molecules made consisting of two or even more atoms. The rules for naming compounds that are covalent are as like this:

1. Write the name of the first element of the formula.
2. Enter“ide” in place of “ide” of the formula, and change the ending“ide “-ide”.
3. Prefixes should be used to indicate number of elements in each element in the molecule. There is no prefix for“mono-” which indicates the number of atoms in the molecule “mono-” for the first element.

Examples:

• CO2 is named carbon dioxide.
• N2O is named dinitrogen monoxide.
• The name SF6 refers to sulfur hexafluoride.

Naming Binary Compounds

Binary compounds consist from two elements. The rules for choosing the proper name for binary compounds is as these:

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

Examples:

• The name HCl refers to hydrogen chloride.
• CO is the name given to carbon monoxide.
• CaO is named calcium oxide.

Practice Exercises

For reinforcement of learning in the classroom, the worksheet contains examples of how to name ionic compound, compounds with covalent bonds or binary substances. These exercises will help students establish a firm 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

By finishing these exercises students will become more confident in labeling chemical compounds. They will also be able to apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an important idea in chemistry. It requires a good understanding of the rules and guidelines for giving different compounds different names. In following the principles laid out in this worksheet, and working through the exercises provided, students are able to quickly identify covalent, ionic, and other binary chemicals. This is a must for the success of chemistry and provides a strong foundation for further studies in the field.
