Chemistry Unit 5 Chemical Bonding And Naming Compounds Worksheet

Chemistry Unit 5 Chemical Bonding And Naming Compounds Worksheet – Naming compounds is a key idea in the field of chemistry. It is about assigning a specific name to any chemical compound based on its composition. A name for a compound contains important information about its properties and its structure. There are various kinds of chemical substances, including the ionic compound, covalent compounds, and binary compounds.

Naming Ionic Compounds

Ionic compounds arise from electron transfer across the atom. They consist mostly of positively charged electrons and negatively charged anions. The rules for naming Ionic compounds are as in the following order:

1. Enter the name of the cation first. Then, write the name of the anion.
2. If the cation is charged with more than one possible charge identify the charge by using Roman numerals that are enclosed in parentheses.
3. In the case of a multiatomic Ion, refer to the name of 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-nitrate.

Naming Covalent Compounds

They are created by the exchange of electrons between atoms. They are made up of molecules composed comprising two or more atoms. The rules for naming covalent compounds are as they are:

1. Then write the name of first element of the formula.
2. Enter the name of the second element of the formula, and change the ending“-ide “-ide”.
3. Use prefixes to indicate the amount of atoms that make up every element of the molecule. Except for“mono,” for example “mono-” for the first element.

Examples:

• CO2 is also known as carbon dioxide.
• N2O is named dinitrogen monoxide.
• The term SF6 stands for sulfur hexafluoride.

Naming Binary Compounds

Binary compounds consist up of two elements. The rules for names for binary compounds are as they are:

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

Examples:

• It is known as hydrogen chloride.
• CO is named carbon monoxide.
• CaO is the term used to describe calcium oxide.

Practice Exercises

To strengthen the understanding and reinforce learning, the worksheet includes the practice of naming ionic and covalent substances in addition to binary compounds. This will help students establish a firm understanding of how 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

Through these exercises, learners will become confident in the naming of chemical compounds and be able apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an important concept in the field of chemistry. It requires a solid understanding of these rules as well as guidelines for names for different kinds of compounds. By adhering to the guidelines set forth in this worksheet, and working with the included activities, students can easily identify ionic, covalent or binary compound. This information is crucial to the success of chemistry and provides a strong foundation for further studies in the field.
