Naming Compounds Worksheet 2 Answers

Naming Compounds Worksheet 2 Answers – Naming of compounds is a fundamental idea in chemistry. It involves assigning a unique name to an chemical compound, based on its composition. It is important to know that the name given to a chemical compound gives important information about its properties and structures. There are different kinds of chemical compound, including Ionic compounds, covalent compounds, and binary compounds.

Naming Ionic Compounds

Ionic compounds are produced by electron transfer across the atom. They are made up from positively charged cations as well as negatively charged anions. The rules for naming these compounds are as in the following order:

1. Write the name of the cation first. Then, write the name of the anion.
2. If the cation has more than one charge then indicate the charge using Roman numerals enclosed in parentheses.
3. If an anion’s structure is polyatomic ion use the name of the ion.

Examples:

• NaCl is named 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 among atoms. They consist of molecules that are made comprising two or more atoms. The guidelines for naming covalent compounds are as they are:

1. Inscribe the name and the first element of the formula.
2. Write your name for the element in the formula, and change the end“ide “-ide”.
3. Prefixes should be used to indicate quantity of atoms contained in every element of the molecule. However, there is no need for“mono-,” the particular prefix “mono-” for the first element.

Examples:

• CO2 is named carbon dioxide.
• N2O is named dinitrogen monoxide.
• The term SF6 stands for sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are compounds made from two elements. The rules for calling binary compounds are as these:

1. Note the name of first element of the formula.
2. Write the name of the second element in the formula, and change the end to “-ide”.

Examples:

• The name of HCl is hydrogen cyanide.
• CO is a chemical compound known as carbon monoxide.
• CaO is the term used to describe calcium oxide.

Practice Exercises

To help reinforce learning to reinforce the learning, the worksheet will contain an exercise to practice naming ionic substances, chemical compounds that are covalent, and other binary chemicals. This will help students develop a solid understanding of what rules are used 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

Through these exercises, students will become more confident in formulating chemical names and be able apply the rules to other compounds.

Conclusion:

Naming compounds is an essential concept in chemistry that requires a deep understanding of principles and regulations for making names for various kinds of compounds. Following the guidelines laid out in this worksheet and experimenting with the included exercises students are able to effectively identify covalent, ionic as well as binary substances. This is a must for being successful in chemistry. It provides an excellent foundation for future research in the field.
