Naming Compounds Containing Polyatomic Ions Worksheet Chapter 7

Naming Compounds Containing Polyatomic Ions Worksheet Chapter 7 – Naming compounds is a basic concept in the field of chemistry. It involves assigning an unique name to each chemical compound according to its composition. When you name a compound contains important information about its properties and structures. There are different kinds of chemical compounds, such as the ionic compound, covalent compounds and binary compounds.

Naming Ionic Compounds

Ionic compounds are formed through moving electrons around atoms. They are composed with positively charged, cations and negatively charged anion. The guidelines for naming ionic compounds are as follows:

1. Inscribe the name of an atom first, followed by the name of the anion.
2. If the cation has more than one charge be sure to identify the charge using Roman numerals in brackets.
3. In the case of a multiatomic ion use the name of the ion.

Examples:

• NaCl is a common name for sodium chloride.
• FeCl3 is known as iron(III) chloride.
• Mg(NO3)2 is known as magnesium nurate.

Naming Covalent Compounds

They are created by sharing electrons among atoms. They consist of molecules that are made by two or many atoms. The guidelines for naming covalent compounds are as below:

1. Name the first element in the formula.
2. Write the name of the second element of the formula, changing the end“ide “-ide”.
3. Use prefixes for the number of elements in each element in the molecule, with“mono,” for example “mono-” for the first element.

Examples:

• CO2 is named carbon dioxide.
• N2O is named dinitrogen monoxide.
• The name SF6 refers to sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are substances made up of two elements. The rules for choosing the proper name for binary compounds is as according to:

1. Note the name of first element in the formula.
2. Write“I” as the title of your second ingredient in the formula, changing the ending to “-ide”.

Examples:

• The name HCl refers to hydrogen chloride.
• CO is the scientific name for carbon monoxide.
• CaO is the name given to calcium oxide.

Practice Exercises

To enhance the learning experience in the classroom, the worksheet contains activities for practicing naming ionic compounds, covalent compounds, along with binary and covalent compounds. The exercises will assist students to achieve a good 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

When they complete these activities, students will build confidence making chemical compounds known and be able to apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an essential concept in chemistry . It requires a good understanding of fundamental rules and principles for naming different types of compounds. Through following the steps laid out in this worksheet, and working with the included exercises students can comfortably identify covalent, ionic and binary compounds. This knowledge is essential for being successful in chemistry. It provides the foundation for future studies in the area.
