Naming Binary Molecular Compounds Worksheet 3

Naming Binary Molecular Compounds Worksheet 3 – Naming compounds is a basic concept in the field of chemistry. It involves the assignment of a unique name to compounds based upon its composition. It is important to know that the name given to a chemical compound will provide crucial information about its properties and structure. There are many types of chemical compounds, such as Ionic compounds, covalent substances, in addition to binary ones.

Naming Ionic Compounds

Ionic compounds are formed by transfers of electrons across atoms. They are made up of positively charged cations as well as negatively charged anions. The rules for naming these compounds are as like this:

1. The name of the cation first, followed by it’s anion’s name.
2. If the cation has multiple possible charges be sure to identify the charge using Roman numerals in parentheses.
3. When the anion has a polyatomic ion, use the name of the ion.

Examples:

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

Naming Covalent Compounds

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

1. Name the first element in the formula.
2. Enter your name for the element in the formula, changing the end“-ide” to “-ide”.
3. Utilize prefixes to represent the number of atoms for every element of the molecule. The exception is“mono-,” the particular prefix “mono-” for the first element.

Examples:

• CO2 is a carbon dioxide derived name.
• N2O is named dinitrogen monoxide.
• SHF6 is the name given to sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are compounds made of two components. The rules for naming binary compounds are as like:

1. Note the name of first element of the formula.
2. Enter“name” of second component in the formula, and change the end“ide “-ide”.

Examples:

• The name of HCl is hydrogen cyanide.
• CO is the abbreviation for carbon monoxide.
• CaO is the term used to describe calcium oxide.

Practice Exercises

To enhance the learning experience for students, the worksheets will include the practice of naming ionic compounds, covalent compounds, or binary substances. These exercises will aid students get a better 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

By completing these exercises, students will have confidence the naming of chemical compounds and be able apply the rules to other compounds.

Conclusion:

Naming compounds is a crucial concept in the field of chemistry. It requires an understanding of how to follow the guidelines and rules for making names for various kinds of compounds. In following the principles laid out in this worksheet and experimenting with the included activities, students are able to successfully identify ionic, chemical, also binary compounds. This is vital for success in chemistry and lays a strong foundation for further research in the field.
