Naming Compounds Chemistry Worksheet Answers

Naming Compounds Chemistry Worksheet Answers – Naming compounds is a key concept in chemical science. It involves giving a unique name to a chemical compound based on its composition. In addition, the name assigned to the compound offers important information on the properties and structure of the compound. There are several kinds of chemical compound, including organic compounds, covalent ones, in addition to binary ones.

Naming Ionic Compounds

Ionic compounds arise from transfers of electrons across atoms. They are composed made up of positively charged anion as well as negatively charged anions. The criteria for naming ionic compounds are as follows:

1. Write the name of cation first. Then, write its name.
2. If the cation could have more than one charge be sure to identify the charge using Roman numerals in parentheses.
3. When the anion has a polyatomic ion, use the name of the Ion.

Examples:

• NaCl is a common name for sodium chloride.
• FeCl3 is named iron(III) chloride.
• Mg(NO3)2 is known under the name magnesium nitrate.

Naming Covalent Compounds

Covalent compounds are formed by the sharing of electrons between atoms. They consist of molecules made from two or more atoms. The rules for naming covalent compounds are as like this:

1. Inscribe the name of the first element of the formula.
2. Write“the name” for the 2nd element of the formula, and change the end to “-ide”.
3. Use prefixes to identify the number of atoms present in each element in the molecule. Except for“mono-,” the particular prefix “mono-” for the first element.

Examples:

• CO2 is named carbon dioxide.
• N2O is named dinitrogen monoxide.
• SF6 is named sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are the ones made from two elements. The rules for calling binary compounds are as the following:

1. Write the name of the first element in the formula.
2. Write in the first element’s name of the formula, changing the ending“-ide” to “-ide”.

Examples:

• Hydrogen chloride is also known as hydrogen.
• CO is named carbon monoxide.
• Calcium oxide is known as CaO.

Practice Exercises

To aid in learning in the classroom, the worksheet contains training exercises to help students name ionic compounds, covalent compounds and binary compounds. These exercises can help students 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
3. BrF3
4. NO

As they complete these exercises students will improve their confidence being able to identify chemical compounds and be able to apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an essential concept in chemistry . It needs a solid understanding what rules apply and the best practices to giving different compounds different names. Following the guidelines outlined in this worksheet, and working by using the included exercises, students can easily identify ionic, covalent the binary chemical compounds. This is vital for succeeding in chemistry and creates an excellent foundation for future studies in the area.
