Naming Compounds Worksheet And Answers

Naming Compounds Worksheet And Answers – Naming compounds is the most fundamental concept in chemistry. It is about assigning a specific 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 structure. There are several kinds of chemical compounds. They include chemical compounds that are ionic, covalent or binary substances.

Naming Ionic Compounds

Ionic compounds form through the transfer of electrons between atoms. They are made up of positively charged cations as well as negatively charged anions. The rules for naming these compounds are as below:

1. Write the name and the Cation first, then what is the name for the anion.
2. If the cation contains more than one charge identify the charge by using Roman numerals enclosed in parentheses.
3. If the anion is a polyatomic Ion, select the name of the Ion.

Examples:

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

Naming Covalent Compounds

They are created by the sharing of electrons between atoms. They consist of molecules that are made comprising two or more atoms. The guidelines for naming compounds that are covalent are as these:

1. Inscribe the name and the first element of the formula.
2. Enter in the first element’s name in the formula, changing the ending to “-ide”.
3. Prefixes can be used to indicate the amount of atoms found in each element in the molecule. There is no prefix for“mono-” which indicates the number of atoms in the molecule “mono-” for the first element.

Examples:

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

Naming Binary Compounds

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

1. Note the name of first element in the formula.
2. Write in the first element’s name in the formula, and change the ending“-ide “-ide”.

Examples:

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

Practice Exercises

To aid in learning The worksheet will provide the practice of naming ionic elements, covalent components, as well as binary compound. The exercises will assist students to get a better understanding of the rules for naming chemical compounds.

Ionic Compound Naming Exercises:

1. Na2S
2. KBr
3. CaF2
4. Al2O3
