Rules For Naming Compounds Worksheet

Rules For Naming Compounds Worksheet – Naming compounds is an important concept in the field of chemistry. It involves granting a unique name to a chemical compound based on its composition. In addition, the name assigned to the chemical compound can provide important information regarding its properties and the structure. There are many types of chemical compounds. These include covalent compounds, ionic compounds, also known as binary compounds.

Naming Ionic Compounds

Ionic compounds form through electron transfer amongst atoms. They are composed from positively charged cations as well as negatively charged anions. The guidelines for naming ionic compounds are as follows:

1. Write the name for the Cation first, then it’s anion’s name.
2. If the cation may have more than one charge make sure to indicate the charge with Roman numerals within parentheses.
3. If an anion’s structure is polyatomic ion you should use the name given to the Ion.

Examples:

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

Naming Covalent Compounds

Covalent compounds are made by the exchange of electrons between atoms. They are composed of molecules made consisting of two or even more atoms. The guidelines for naming covalent compounds are as like this:

1. Inscribe the name of the first element of the formula.
2. Enter in the first element’s name in the formula, changing the end in the form of “-ide”.
3. Use prefixes to identify the quantity of atoms contained 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 also known as carbon dioxide.
• N2O is named dinitrogen monoxide.
• It is also known as sulfur hexafluoride.

Naming Binary Compounds

Compounds that are binary are those made by two elements. The rules for the naming of binary compounds are as according to:

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

Examples:

• Hydrogen chloride is the name given to it.
• CO is a chemical compound known as carbon monoxide.
• The name CaO comes from calcium oxide.

Practice Exercises

In order to reinforce the learning process and reinforce learning, the worksheet includes practices for naming ionic compound, compounds with covalent bonds,, and other binary chemicals. These exercises will help students achieve a good 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:
