6.2 Worksheet Naming Compounds

6.2 Worksheet Naming Compounds – Naming compounds is a fundamental concept in chemical science. It is the process of assigning a distinct name to each chemical compound according to its composition. It is important to know that the name given to a chemical compound contains important information about the properties and structure of the compound. There are various kinds of chemical compound, including chemical compounds that are ionic, covalent,, and even binary compounds.

Naming Ionic Compounds

Ionic compounds are formed through electron transfer amongst atoms. They consist mostly of positively charged electrons and negatively charged anion. The rules of naming ionic compounds are as below:

1. Write the name of the Cation first, then an anion’s name.
2. If the cation could have more than one charge, indicate the charge using Roman numerals within parentheses.
3. For anion that is not a polyatomic ion use the name of the ion.

Examples:

• NaCl is also known as sodium cyanide.
• FeCl3 is known as iron(III) chloride.
• Mg(NO3)2 is known under the name magnesium nitrate.

Naming Covalent Compounds

Covalent compounds are created through the sharing of electrons among atoms. They are composed of molecules made by two or more atoms. The rules for naming covalent compounds are as they are:

1. Write the name of the first element of the formula.
2. Write your name for the element of the formula, and change the end“ide “-ide”.
3. Use prefixes for the number of atoms in every element of the molecule. This is not the case for“mono-,” the particular prefix “mono-” for the first element.

Examples:

• Carbon dioxide is the name of CO2.
• N2O is named dinitrogen monoxide.
• The name SF6 refers to sulfur hexafluoride.

Naming Binary Compounds

Binary compounds consist up of two elements. The rules for naming binary compounds are as according to:

1. Enter the name of the first element of the formula.
2. Write“I” as the title of your second ingredient of the formula, and change the ending“-ide” to “-ide”.

Examples:

• The name of HCl is hydrogen cyanide.
• CO is the name given to carbon monoxide.
• The name CaO comes from calcium oxide.

Practice Exercises

In order to reinforce the learning process this worksheet will offer drills for naming Ionic elements, covalent components in addition to binary compounds. These exercises will aid students acquire a deep understanding the rules that govern the naming of 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 become more confident in being able to identify chemical compounds and be able to apply the rules to other compounds.

Conclusion:

Naming compounds is an important concept in chemistry , and demands a firm understanding the rules and guidelines to creating names for different kinds and types of compounds. In following the principles laid out in this worksheet, and working with the included activities, students can be confident in naming ionic, covalent, and binary compounds. This is vital for being successful in chemistry. It provides a strong foundation for further studies in the field.
