Naming Compounds And Writing Formulas Worksheet

Naming Compounds And Writing Formulas Worksheet – Naming compounds is a fundamental concept in chemistry. It is the process of assigning a distinct name to chemicals based on its composition. What is the title of a chemical compound will provide crucial information about the properties and structure of the compound. There are different types of chemical compounds, including ionic compounds, covalent compounds, along with binary and covalent compounds.

Naming Ionic Compounds

Ionic compounds can be formed by an exchange of electrons among atoms. They consist from positively charged cations and negatively charged anion. The guidelines for naming ionic compounds are as follows:

1. Write the name and the Cation first, then what is the name for the anion.
2. If the cation is charged with multiple possible charges, indicate the charge using Roman numerals enclosed in parentheses.
3. If it is a polyatomic Ion, use the name of the ion.

Examples:

• NaCl is also known as sodium cyanide.
• FeCl3 is known as iron(III) chloride.
• Mg(NO3)2 is also known as magnesium nitrate.

Naming Covalent Compounds

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

1. Inscribe the name and the first element of the formula.
2. Write“the name” for the 2nd element of the formula, and change the end“-ide. “-ide”.
3. Utilize prefixes to represent the amount of atoms that make up each element in the molecule. The exception is“mono,” for example “mono-” for the first element.

Examples:

• CO2 is named carbon dioxide.
• N2O is named dinitrogen monoxide.
• It is also known as sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are compounds made by two elements. The rules for naming binary compounds are as these:

1. Inscribe the name of the first element of the formula.
2. Write in the first element’s name in the formula, and change the ending“-ide “-ide”.

Examples:

• Hydrogen chloride is also known as hydrogen.
• CO is a synonym for carbon monoxide.
• CaO is the name given to calcium oxide.

Practice Exercises

To enhance the learning experience and reinforce learning, the worksheet includes drills for naming Ionic molecules, covalent compound also known as binary compounds. The exercises will assist students to achieve a good understanding of the rules 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

As they complete these exercises students will improve their confidence naming chemical compounds and will be able to apply these rules to other compounds.

Conclusion:

Naming compounds is an important concept in the field of chemistry. It requires a deep understanding of basic rules and procedures to Naming different kinds of compounds. In following the principles laid out in this worksheet and experimenting through the exercises provided, students will be able to quickly identify covalent, ionic along with binary and covalent compounds. This skill is essential to achievement in chemistry. It will also provide a strong foundation for further research in the field.
