Naming Covalent Compounds Worksheet 3

Naming Covalent Compounds Worksheet 3 – Naming compounds is the most fundamental concept in chemistry. It involves the assignment of a unique name to an chemical compound, based on its composition. An individual’s name on a chemical compound will provide crucial information about the properties and structure of the compound. There are many types that chemical compounds can be found, including those with ionic properties, covalent compound, and binary compounds.

Naming Ionic Compounds

Ionic compounds are produced by electron transfer across the atom. They are composed mostly of positively charged electrons as well as negatively charged anions. The rules of naming ionic compounds are as they are:

1. Write the name and the Cation first, then what is the name for the anion.
2. If the cation could have multiple possible charges Indicate the charge using Roman numerals inside parentheses.
3. If the anion is a polyatomic Ion, refer to the name of anion.

Examples:

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

Naming Covalent Compounds

Covalent compounds form through sharing electrons among atoms. They consist of molecules that are made from two or more atoms. The guidelines for naming compounds that are covalent are as below:

1. Write the name for the first element of the formula.
2. Write the name of the second element of the formula, and change the ending“-ide. “-ide”.
3. Use prefixes to identify the amount of atoms that make up each element in the molecule. Except for“mono” as a prefix “mono-” for the first element.

Examples:

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

Naming Binary Compounds

Compounds that are binary are those made from two elements. The rules for names for binary compounds are as according to:

1. Write the name for the first element in the formula.
2. Enter an appropriate name for each element of the formula, changing the end to “-ide”.

Examples:

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

Practice Exercises

For reinforcement of learning for students, the worksheets will include training exercises to help students name ionic substances, chemical compounds that are covalent, also known as binary compounds. These exercises will allow students to improve their 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

When they complete these activities, students will gain confidence in understanding chemical compound names and be able to apply these rules to other chemical compounds.

Conclusion:

Naming compounds is an essential idea in chemistry. It requires a good understanding of how to follow the guidelines and rules to making names for various kinds of compounds. By adhering to the guidelines set forth in this worksheet and practicing using the activities included, students can quickly identify covalent, ionic the binary chemical compounds. This knowledge is vital to the success of chemistry and provides the foundation for future studies in the area.
