Writing And Naming Compounds Worksheet

Writing And Naming Compounds Worksheet – Naming chemical compounds is an essential concept in chemistry. It involves assigning a distinctive name to compounds based upon its composition. In addition, the name assigned to the chemical compound gives important information about its properties and structures. There are many types of chemical compounds, including covalent compounds, ionic compounds in addition to binary ones.

Naming Ionic Compounds

Ionic compounds are produced by the transfer of electrons between atoms. They are made up from positively charged cations and negatively charged anion. The rules for naming ionic compounds are as the following:

1. Enter the name of the initial cation, followed by it’s anion’s name.
2. If the cation is charged with more than one possible charge Indicate the charge using Roman numerals inside parentheses.
3. In the case of a multiatomic ion you should use the name given to the ion.

Examples:

• NaCl is named 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 composed of molecules made by two or more atoms. The rules for naming compounds that are covalent are as according to:

1. Inscribe the name and the first element in the formula.
2. Enter“name” of second component in the formula, changing the ending to “-ide”.
3. Prefixes can be used to indicate the amount of atoms found in every element of the molecule. The exception is“mono” as a prefix “mono-” for the first element.

Examples:

• Carbon dioxide is the name of CO2.
• N2O is named dinitrogen monoxide.
• It is also known as sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are those made from two elements. The rules for naming binary compounds are as in the following order:

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

Examples:

• The term hydrogen chloride refers to the HCl.
• CO is the scientific name for carbon monoxide.
• CaO is the term used to describe calcium oxide.

Practice Exercises

To strengthen the understanding to reinforce the learning, the worksheet will contain activities for practicing naming ionic compound, compounds with covalent bonds along with binary and covalent compounds. These exercises will help students acquire a deep understanding the rules used to name 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 completing these exercises, students will build confidence labeling chemical compounds. They will also be able apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an important idea in chemistry that demands a firm understanding what rules apply and the best practices for giving different compounds different names. By adhering to the guidelines set forth in this worksheet, and working through the exercises provided, students are able to confidently name ionic, covalent also binary compounds. This knowledge is essential for success in chemistry . It also provides the foundation for future studies in the field.
