Naming And Writing Covalent Compounds Worksheet Answers

Naming And Writing Covalent Compounds Worksheet Answers – Naming compounds is a fundamental idea in chemistry. It is about assigning a specific name to any chemical compound based on its composition. The name of a compound provides crucial information about its properties and structure. There are different kinds of chemical compounds, such as the ionic compound, covalent compounds and binary compounds.

Naming Ionic Compounds

Ionic compounds are formed by an exchange of electrons among atoms. They are made up with positively charged, cations and negatively charged anion. The guidelines for naming ionic compounds are as like this:

1. Enter the name of the an atom first, followed by that of the anion.
2. If the cation is charged with more than one possible charge be sure to identify the charge using Roman numerals enclosed in parentheses.
3. If the anion is a polyatomic ion, you should use the name given to the ion.

Examples:

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

Naming Covalent Compounds

Compounds that are covalent are formed through the sharing of electrons between atoms. They consist of molecules that are made by two or more atoms. The guidelines for naming compounds that are covalent are as in the following order:

1. Inscribe the name and the first element in the formula.
2. Enter an appropriate name for each element of the formula, and change the end“-ide “-ide”.
3. Prefixes indicate the number of atoms of each element in the molecule, with“mono,” which is the name of the element “mono-” for the first element.

Examples:

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

Naming Binary Compounds

Binary compounds are those made by two elements. The rules for names for binary compounds are as follows:

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

Examples:

• Hydrogen chloride is also known as hydrogen.
• CO is the scientific name 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 practice exercises for naming ionic compounds, covalent compounds including binary ones. These exercises can help students establish a firm 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
3. BrF3
4. NO

Through these exercises, students will be confident in the naming of chemical compounds and be able to apply these rules to other compounds.

Conclusion:

Naming compounds is a crucial aspect of chemistry that demands a firm understanding principles and regulations to naming different types of compounds. Through following the steps laid out in this worksheet, and working through the exercises provided, students can easily identify ionic, covalent in addition to binary, compounds. This information is crucial to an effective chemistry education and forms the foundation for further research in the field.
