Naming Molecular Compounds Worksheet 6c

Naming Molecular Compounds Worksheet 6c – Naming of compounds is a fundamental concept in chemistry. It involves assigning a distinctive name to one chemical substance based on its composition. It is important to know that the name given to a compound provides important information about its properties and structure. There are a variety of chemical compounds. They include covalent compounds, ionic compounds,, and even binary compounds.

Naming Ionic Compounds

The Ionic compound is formed by electron transfer between electrons. They consist mostly of positively charged electrons as well as negatively charged anions. The guidelines for naming ionic compounds are as in the following order:

1. Inscribe the name of cation first, followed by what is the name for the anion.
2. If the cation has more than one possible charge then indicate the charge using Roman numerals that are enclosed in parentheses.
3. In the case of a multiatomic ion you should use the name given to the anion.

Examples:

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

Naming Covalent Compounds

Covalent compounds are created through the exchange of electrons between atoms. They are made up of molecules composed by two or more atoms. The rules for naming compounds that are covalent are as like this:

1. Inscribe the name and the first element of the formula.
2. Enter“Element 2” as the title in the formula, and change the ending“-ide” to “-ide”.
3. Use prefixes to identify the number of elements in every element of the molecule. This is not the case 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.
• It is also known as sulfur hexafluoride.

Naming Binary Compounds

Binary compounds consist from two elements. The rules for the naming of binary compounds are as they are:

1. Write the name of the first element of the formula.
2. Enter“I” as the title of your second ingredient of the formula, and change the ending to “-ide”.

Examples:

• It is known as hydrogen chloride.
• CO is named carbon monoxide.
• CaO is named calcium oxide.

Practice Exercises

To help reinforce learning to reinforce the learning, the worksheet will contain drills for naming Ionic molecules, covalent compound including binary ones. The exercises will assist students to acquire a deep understanding the rules that govern the naming of 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 gain confidence in being able to identify chemical compounds and be able apply the rules to other chemical compounds.

Conclusion:

Naming compounds is a crucial concept in chemistry that requires a thorough understanding of what rules apply and the best practices for giving different compounds different names. By adhering to the guidelines set forth in this worksheet and practicing with the included activities, students will be able successfully identify ionic, chemical, as well as binary substances. This knowledge is essential for being successful in chemistry. It provides the foundation for future studies in the field.
