Chapter 7 Naming Compounds Containing Polyatomic Ions Worksheet Answers

Chapter 7 Naming Compounds Containing Polyatomic Ions Worksheet Answers – Naming chemical compounds is an essential concept in chemical science. It is about assigning a specific name to each chemical compound according to its composition. Names of chemical compound is a crucial indicator of its properties and structures. There are different types of chemical compounds, including those with ionic properties, covalent compound, also known as binary compounds.

Naming Ionic Compounds

Ionic compounds are created by an exchange of electrons among atoms. They are made up mostly of positively charged electrons as well as negatively charged anion. The rules for naming Ionic compounds are as the following:

1. Enter the name of the Cation first, then it’s anion’s name.
2. If the cation could have more than one charge be sure to identify the charge using Roman numerals inside parentheses.
3. If it is a polyatomic ion make use of the name for the Ion.

Examples:

• NaCl is a synonym for sodium chloride.
• FeCl3 is known as 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 consist of molecules that are made from two or more atoms. The rules for naming covalent compounds are as like this:

1. Write the name of the first element of the formula.
2. Enter“the name” for the 2nd element in the formula, and change the end“-ide” to “-ide”.
3. Prefixes indicate the number of atoms of each element in the molecule. The exception is“mono-” which indicates the number of atoms in the molecule “mono-” for the first element.

Examples:

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

Naming Binary Compounds

Compounds that are binary are those made of two components. The rules for using the term binary compound are as follows:

1. Write the name and the first element in the formula.
2. Write your name for the element of the formula, changing the end“-ide” to “-ide”.

Examples:

• Hydrogen chloride is the name given to it.
• CO is the abbreviation for carbon monoxide.
• CaO is named calcium oxide.

Practice Exercises

To reinforce the learning and reinforce learning, the worksheet includes activities for practicing naming ionic and covalent substances along with binary and covalent compounds. These exercises can help students acquire a deep understanding the principles 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

As they complete these exercises students will develop confidence in naming chemical compounds and will be able apply the rules to other compounds.

Conclusion:

Naming compounds is an important idea in chemistry that requires a solid understanding of the rules and guidelines for making names for various kinds of compounds. In following the principles laid out in this worksheet and practicing through the exercises provided, students can confidently name ionic, covalent, as well as binary substances. This knowledge is essential for being successful in chemistry. It provides the foundation for future studies in the area.
