Writing Formulas And Naming Molecular Compounds Worksheet

Writing Formulas And Naming Molecular Compounds Worksheet – Naming chemical compounds is an essential concept in chemical science. It involves the assignment of a unique name to an chemical compound, based on its composition. When you name a chemical compound gives important information about its properties and its structure. There are many types of chemical compounds, including Ionic compounds, covalent substances, or binary substances.

Naming Ionic Compounds

Ionic compounds form through an exchange of electrons among atoms. They consist with positively charged, cations and negatively charged anions. The criteria for naming ionic compounds are as according to:

1. The name of the catalytic cation in the first place, then that of the anion.
2. If the cation has more than one charge Indicate the charge with Roman numerals that are enclosed in parentheses.
3. In the case of a multiatomic Ion, use the name of the anion.

Examples:

• NaCl is also known as 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 created through the sharing of electrons among atoms. They consist of molecules made consisting of two or more atoms. The rules for naming covalent compounds are as the following:

1. Then write the name of first element in the formula.
2. Write“the name” for the 2nd element in the formula, changing the end to “-ide”.
3. Use prefixes to identify the number of elements in every element of the molecule. Except for using the suffix “mono-” for the first element.

Examples:

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

Naming Binary Compounds

Binary compounds consist by two elements. The rules for choosing the proper name for binary compounds is as in the following order:

1. Enter the name of the first element of the formula.
2. Write an appropriate name for each element in the formula, and change the ending“-ide. “-ide”.

Examples:

• Hydrogen chloride is the name given to it.
• CO is the name given to carbon monoxide.
• Calcium oxide is known as CaO.

Practice Exercises

To further reinforce the learning in the classroom, the worksheet contains examples of how to name ionic compounds, covalent compounds, as well as binary compound. These exercises can help students get a better understanding of the rules of 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

After completing these tasks, students will gain confidence in the naming of chemical compounds and be able to apply these rules to other chemical compounds.

Conclusion:

Naming compounds is a crucial notion in chemistry and requires a solid understanding of how to follow the guidelines and rules for calling different kinds of compounds. When following the guidelines provided in this worksheet and experimenting using the provided exercises, students can comfortably identify covalent, ionic the binary chemical compounds. The knowledge gained is essential for achievement in chemistry. It will also provide a strong foundation for further studies in the field.
