Naming Compounds Rules Worksheet

Naming Compounds Rules Worksheet – Naming compounds is a fundamental idea in chemical science. It is the process of assigning a distinct name to one chemical substance based on its composition. What is the title of a chemical compound gives important information about its properties and structures. There are many types that chemical compounds can be found, including ionic compounds, covalent compounds, in addition to binary ones.

Naming Ionic Compounds

The Ionic compound is formed by electron transfer amongst atoms. They are composed comprise positively charged Cations and negatively charged anions. The rules for naming Ionic compounds are as follows:

1. Write the name and the initial cation, followed by its name.
2. If the cation is charged with more than one possible charge make sure to indicate the charge with Roman numerals that are enclosed in parentheses.
3. If the anion is a polyatomic ion choose the name of the anion.

Examples:

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

Naming Covalent Compounds

Covalent compounds are made by sharing electrons among atoms. They consist of molecules that are made from two or more atoms. The guidelines for naming compounds that are covalent are as according to:

1. Inscribe the name and the first element in the formula.
2. Enter the name of the second element of the formula, and change the end“-ide. “-ide”.
3. Prefixes indicate the number of atoms present in each element in the molecule. Except 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.
• The name SF6 refers to sulfur hexafluoride.

Naming Binary Compounds

Binary compounds consist of two components. The rules for names of binary compounds can be described as in the following order:

1. Write the name and the first element in the formula.
2. Write“double element” of the formula, and change the end in the form of “-ide”.

Examples:

• The name of HCl is hydrogen cyanide.
• CO is also known as carbon monoxide.
• CaO is also known as calcium oxide.

Practice Exercises

To aid in learning to reinforce the learning, the worksheet will contain practice exercises for naming ionic molecules, covalent compound, or binary substances. These activities will help students improve their understanding of 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

Through these exercises, students will become more confident in making chemical compounds known and be able to apply these rules to other chemical compounds.

Conclusion:

Naming compounds is an essential concept in chemistry , and needs a solid understanding basic rules and procedures to Naming different kinds of compounds. In following the principles laid out in this worksheet, and working with the included exercises students are able to easily identify ionic, covalent, and binary compounds. This is vital for achievement in chemistry. It will also provide solid foundations for further studies in the area.
