Naming Compounds Worksheet With Answer Key

Naming Compounds Worksheet With Answer Key – Naming chemical compounds is an essential concept in the field of chemistry. It involves granting a unique name to a chemical compound based on its composition. An individual’s name on a compound provides important information about its properties and the structure. There are various types of chemical substances, including Ionic compounds, covalent substances along with binary and covalent compounds.

Naming Ionic Compounds

Ionic compounds are formed by an exchange of electrons among atoms. They are composed with positively charged, cations as well as negatively charged anions. The rules for naming Ionic compounds are as they are:

1. Note the name of the an atom first, followed by it’s anion’s name.
2. If the cation has more than one possible charge then indicate the charge using Roman numerals within parentheses.
3. For anion that is not a polyatomic Ion, select the name of the anion.

Examples:

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

Naming Covalent Compounds

Covalent compounds arise from the sharing of electrons between atoms. They consist of molecules that are made consisting of two or even more atoms. The guidelines for naming compounds that are covalent are as according to:

1. Note the name of first element of the formula.
2. Enter“the name” for the 2nd element in the formula, changing the ending“-ide” to “-ide”.
3. Prefixes indicate the number of elements in each element in the molecule. This is not the case for“mono” as a prefix “mono-” for the first element.

Examples:

• CO2 is a carbon dioxide derived name.
• N2O is named dinitrogen monoxide.
• The term SF6 stands for sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are composed from two elements. The rules for calling binary compounds are as they are:

1. Inscribe the name of the first element of the formula.
2. Enter in the first element’s name in the formula, changing the ending“-ide “-ide”.

Examples:

• HCl is named hydrogen chloride.
• CO is the abbreviation for carbon monoxide.
• CaO is a name for calcium oxide.

Practice Exercises

To strengthen the understanding it will be accompanied by an exercise to practice naming ionic elements, covalent components also known as binary compounds. These exercises will allow students to build a solid understanding of the rules 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

In completing these tests, students will build confidence the naming of chemical compounds and be able apply the rules to other compounds.

Conclusion:

Naming compounds is an important aspect of chemistry that requires a deep understanding of the rules and guidelines for making names for various kinds of compounds. If you follow the rules laid out in this worksheet and experimenting using the provided exercises, students will be able quickly identify covalent, ionic, as well as binary substances. This is vital for succeeding in chemistry and creates solid foundations for further research in the area.
