Chapter 2 Practice Worksheet Naming Compounds And Writing Formulas

Chapter 2 Practice Worksheet Naming Compounds And Writing Formulas – Naming compounds is the most fundamental concept in chemical science. It involves giving a unique name to each chemical compound according to its composition. In addition, the name assigned to the chemical compound will provide crucial information about the properties and structure of the compound. There are many types of chemical compounds. This includes chemical compounds that are ionic, covalent, along with binary and covalent compounds.

Naming Ionic Compounds

The Ionic compound is formed by transfers of electrons across atoms. They consist comprise positively charged Cations as well as negatively charged anions. The rules for naming these compounds are as according to:

1. Inscribe the name of cation first. Then, write names of anion.
2. If the cation may have multiple possible charges Indicate the charge with Roman numerals in brackets.
3. The anion must be a polyatomic ion identify the anion.

Examples:

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

Naming Covalent Compounds

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

1. Write the name of the first element of the formula.
2. Write“name” of second component of the formula, changing the end in the form of “-ide”.
3. Prefixes are used to indicate the number of atoms for every element of the molecule. There is no prefix for“mono,” for example “mono-” for the first element.

Examples:

• Carbon dioxide is the name of CO2.
• N2O is named dinitrogen monoxide.
• SHF is also known as sulfur Hexafluoride.

Naming Binary Compounds

Binary compounds are made by two elements. The rules for the naming of binary compounds are as the following:

1. Write the name for the first element of the formula.
2. Enter in the first element’s name in the formula, and change the end“-ide. “-ide”.

Examples:

• It is known as hydrogen chloride.
• CO is the name given to carbon monoxide.
• CaO is the name given to calcium oxide.

Practice Exercises

To reinforce the learning and reinforce learning, the worksheet includes an exercise to practice naming ionic molecules, covalent compound, along with binary and covalent compounds. These exercises will aid students 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

After completing these tasks, students will build confidence the naming of chemical compounds and be able apply the rules to other chemical compounds.

Conclusion:

Naming compounds is a crucial idea in chemistry that requires a solid understanding of fundamental rules and principles for names for different kinds of compounds. In following the principles laid out in this worksheet, and working by using the included exercises, students are able to be confident in naming ionic, covalent, and other binary chemicals. The knowledge gained is essential for the success of chemistry and provides the foundation for further studies in the field.
