Naming Binary Molecular Compounds Worksheet Answer Key

Naming Binary Molecular Compounds Worksheet Answer Key – Naming compounds is an essential idea in chemistry. It involves assigning a unique name to the chemical compound on the basis of its composition. Names of chemical compound offers important information on its properties and its structure. There are different types of chemical compounds. These include chemical compounds that are ionic, covalent and binary compounds.

Naming Ionic Compounds

The Ionic compound is formed by electron transfer amongst atoms. They are made up from positively charged cations and negatively charged anion. The rules for naming ionic compounds are as according to:

1. Note the name of the compound first, and then an anion’s name.
2. If the cation may have more than one charge be sure to identify the charge using Roman numerals enclosed in parentheses.
3. When the anion has a polyatomic ion make use of the name for the Ion.

Examples:

• NaCl is the name given to sodium chloride.
• FeCl3 is also known as iron(III) chloride.
• Mg(NO3)2 is known as magnesium nurate.

Naming Covalent Compounds

Covalent compounds form through the sharing of electrons among atoms. They consist of molecules that are made from two or more atoms. The rules for naming compounds that are covalent are as in the following order:

1. Note the name of first element of the formula.
2. Write in the first element’s name of the formula, changing the ending“ide “-ide”.
3. Prefixes can be used to indicate the amount of atoms found in every element of the molecule. There is no prefix for the prefix “mono-” for the first element.

Examples:

• CO2 is also known as carbon dioxide.
• N2O is named dinitrogen monoxide.
• The name SF6 refers to sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are composed from two elements. The rules for naming binary compounds are as the following:

1. Note the name of first element of the formula.
2. Write“name” of second component in the formula, changing the end to “-ide”.

Examples:

• Hydrogen chloride is the name given to it.
• CO is the name given to carbon monoxide.
• CaO is the term used to describe calcium oxide.

Practice Exercises

To aid in learning this worksheet will offer practices for naming ionic compound, compounds with covalent bonds as well as binary compound. These exercises will allow students to get a better 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:

1. Cl2O7
2. P2S5

4. NO

After completing these tasks, students will improve their confidence labeling chemical compounds. They will also be able to apply these rules to other compounds.

Conclusion:

Naming compounds is an essential notion in chemistry and requires a deep understanding of specific rules for naming different types of compounds. Through following the steps laid out in this worksheet and experimenting with the included exercises students will be able to quickly identify covalent, ionic as well as binary substances. This information is crucial to the success of chemistry and provides solid foundations for further research in the field.
