Naming Covalent Compounds Worksheet Chapter 6.5 Answer Key

Naming Covalent Compounds Worksheet Chapter 6.5 Answer Key – Naming compounds is the most fundamental idea in chemistry. It involves assigning an unique name to a chemical compound based on its composition. When you name a compound contains important information about its properties and the structure. There are different types of chemical compounds, such as covalent compounds, ionic compounds, and even binary compounds.

Naming Ionic Compounds

Ionic compounds arise from electron transfer between electrons. They consist from positively charged cations as well as negatively charged anion. The rules of naming ionic compounds are as the following:

1. Enter the name of the an atom first, followed by what is the name for the anion.
2. If the cation is charged with more than one possible charge Indicate the charge with Roman numerals inside parentheses.
3. The anion must be a polyatomic ion refer to the name of Ion.

Examples:

• NaCl is the name given to sodium chloride.
• FeCl3 is known as iron(III) chloride.
• Mg(NO3)2 is known under the name magnesium nitrate.

Naming Covalent Compounds

Covalent compounds form through the sharing of electrons among atoms. They consist of molecules that are made comprising two or more atoms. The guidelines for naming covalent compounds are as in the following order:

1. Name the first element of the formula.
2. Enter“the name” for the 2nd element in the formula, changing the ending to “-ide”.
3. Prefixes can be used to indicate the number of atoms present in each element in the molecule. This is not the case for using the suffix “mono-” for the first element.

Examples:

• CO2 is the name given to carbon dioxide.
• N2O is named dinitrogen monoxide.
• So, SF6 is a sulfur hexafluoride.

Naming Binary Compounds

Binary compounds consist of two components. The rules for choosing the proper name for binary compounds is as follows:

1. Note the name of first element in the formula.
2. Write an appropriate name for each element in the formula, changing the end in the form of “-ide”.

Examples:

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

Practice Exercises

To reinforce the learning for students, the worksheets will include examples of how to name ionic compounds, covalent compounds, and other binary chemicals. This will help students improve their understanding of 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

In completing these tests, students will become more confident in naming chemical compounds and will be able to apply these rules to other compounds.

Conclusion:

Naming compounds is an essential notion in chemistry and requires a thorough understanding of specific rules to calling different kinds of compounds. If you follow the rules laid out in this worksheet and experimenting with the included exercises, students can quickly identify covalent, ionic, in addition to binary, compounds. This skill is essential to success in chemistry and lays a strong foundation for further studies in the field.
