Writing Formulas And Naming Compounds Worksheet

Writing Formulas And Naming Compounds Worksheet – Naming chemical compounds is an essential concept in the field of chemistry. It involves assigning a distinctive name to the chemical compound on the basis of its composition. What is the title of a chemical compound will provide crucial information about its properties and the structure. There are a variety of chemical compounds, such as Ionic compounds, covalent substances or binary substances.

Naming Ionic Compounds

The Ionic compound is formed by electron transfer amongst atoms. They are composed of negatively charged cations and negatively charged anions. The rules of naming ionic compounds are as like this:

1. Inscribe the name of cation first, followed by names of anion.
2. If the cation may have more than one charge Indicate the charge using Roman numerals in parentheses.
3. For anion that is not a polyatomic Ion, identify the ion.

Examples:

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

Naming Covalent Compounds

The formation of covalent compounds is caused by sharing electrons among atoms. They consist of molecules made consisting of two or even more atoms. The guidelines for naming compounds that are covalent are as they are:

1. Write the name for the first element in the formula.
2. Write“ide” in place of “ide” of the formula, changing the ending to “-ide”.
3. Use prefixes to indicate the quantity of atoms contained in each element in the molecule. However, there is no need for“mono-” for the first element “mono-” for the first element.

Examples:

• CO2 is the name given to carbon dioxide.
• N2O is named dinitrogen monoxide.
• The term SF6 stands for sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are those made of two components. The rules for names for binary compounds are as follows:

1. Then write the name of first element in the formula.
2. Enter“name” of second component of the formula, and change the end“-ide” to “-ide”.

Examples:

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

Practice Exercises

To help reinforce learning The worksheet will provide activities for practicing naming ionic chemicals, compound covalent, along with binary and covalent compounds. These exercises will allow students to improve their 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

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

Conclusion:

Naming compounds is an important idea in chemistry that requires a deep understanding of these rules as well as guidelines to Naming different kinds of compounds. In following the principles laid out in this worksheet, and working through the exercises provided, students are able to confidently name ionic, covalent, and binary compounds. This information is crucial to being successful in chemistry. It provides the foundation for future research in the field.
