Naming Covalent Compounds Practice Worksheet Answer Key

Naming Covalent Compounds Practice Worksheet Answer Key – Naming compounds is the most fundamental concept in chemical science. It involves assigning an unique name to any chemical compound based on its composition. Names of chemical compound is a crucial indicator of its properties and the structure. There are various types of chemical compounds. This includes the ionic compound, covalent compounds, and even binary compounds.

Naming Ionic Compounds

Ionic compounds are created by an exchange of electrons among atoms. They are composed in positively charged caustics as well as negatively charged anion. The criteria for naming ionic compounds are as like this:

1. Write the name of the cation first, followed by your name and the name of the anion.
2. If the cation could have more than one possible charge mark the charge in Roman numbers enclosed in parentheses.
3. When the anion has a polyatomic ion, take the name of that anion.

Examples:

• NaCl is named sodium chloride.
• FeCl3 is known as iron(III) chloride.
• Mg(NO3)2 is known as magnesium Nitrate.

Naming Covalent Compounds

Compounds that are covalent are formed through the exchange of electrons between atoms. They are composed of molecules made by two or more atoms. The rules for naming covalent compounds are as the following:

1. Inscribe the name and the first element of the formula.
2. Enter in the first element’s name in the formula, changing the end“-ide. “-ide”.
3. Prefixes can be used to indicate the number of atoms in every element of the molecule, with“mono-” which indicates the number of atoms in the molecule “mono-” for the first element.

Examples:

• CO2 is also known as carbon dioxide.
• N2O is named dinitrogen monoxide.
• This is known as sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are composed from two elements. The rules for names for binary compounds are as below:

1. Write the name for the first element of the formula.
2. Write“double element” of the formula, and change the end“-ide. “-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

To further reinforce the learning to reinforce the learning, the worksheet will contain practices for naming ionic and covalent substances, along with binary and covalent compounds. The exercises will assist students to improve their understanding of the rules of 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

By completing these exercises, students will build confidence labeling chemical compounds. They will also be able to apply these rules to other chemical compounds.

Conclusion:

Naming compounds is an essential idea in chemistry. It demands a firm understanding fundamental rules and principles to calling different kinds of compounds. Following the guidelines laid out in this worksheet and experimenting with the included activities, students are able to comfortably identify covalent, ionic in addition to binary, compounds. The knowledge gained is essential for success in chemistry and lays the foundation for future research in the area.
