Naming And Writing Formulas For Covalent Molecular Compounds Worksheet Answers

Naming And Writing Formulas For Covalent Molecular Compounds Worksheet Answers – Naming compounds is a fundamental idea in chemical science. It is the process of assigning a distinct name to an chemical compound, based on its composition. A name for a compound contains important information about the properties and structure of the compound. There are different kinds of chemical compounds. This includes those with ionic properties, covalent compound, or binary substances.

Naming Ionic Compounds

Ionic compounds form through transfers of electrons across atoms. They are made up in positively charged caustics as well as negatively charged anion. The rules for naming ionic compounds are as these:

1. The name of the Cation first, then its name.
2. If the cation may have more than one possible charge then indicate the charge using Roman numerals within parentheses.
3. For anion that is not a polyatomic Ion, use the name of the anion.

Examples:

• NaCl is a common name for sodium chloride.
• FeCl3 is known as iron(III) chloride.
• Mg(NO3)2 is known under the name 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 consisting of two or more atoms. The rules for naming covalent compounds are as the following:

1. Note the name of first element in the formula.
2. Write in the first element’s name in the formula, and change the end to “-ide”.
3. Use prefixes to identify the number of atoms of every element of the molecule. However, there is no need for“mono-” which indicates the number of atoms in the molecule “mono-” for the first element.

Examples:

• Carbon dioxide is the name of CO2.
• N2O is named dinitrogen monoxide.
• It is also known as sulfur hexafluoride.

Naming Binary Compounds

Compounds that are binary are those made by two elements. The rules for names of binary compounds can be described as according to:

1. Write the name for the first element of the formula.
2. Write“Name” for second element of the formula, changing the ending in the form of “-ide”.

Examples:

• Hydrogen chloride is the name given to it.
• CO is also known as carbon monoxide.
• Calcium oxide is known as CaO.

Practice Exercises

To help reinforce learning, the worksheet will include training exercises to help students name ionic compounds, covalent compounds and binary compounds. This will help students establish a firm 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

As they complete these exercises students will gain confidence in formulating chemical names and be able to apply these rules to other compounds.

Conclusion:

Naming compounds is an essential concept in the field of chemistry. It requires a thorough understanding of fundamental rules and principles for creating names for different kinds and types of compounds. Through following the steps laid out in this worksheet and practicing using the activities included, students can be confident in naming ionic, covalent and other binary chemicals. This information is crucial to an effective chemistry education and forms a strong foundation for further studies in the area.
