Naming Compounds And Writing Formulas Extra Practice Worksheet

Naming Compounds And Writing Formulas Extra Practice Worksheet – Naming chemical compounds is an essential concept in the field of chemistry. It involves the assignment of a unique name to each chemical compound according to its composition. It is important to know that the name given to a compound provides crucial information about the properties and structure of the compound. There are various types of chemical compounds. They include the ionic compound, covalent compounds, and even binary compounds.

Naming Ionic Compounds

The Ionic compound is formed by moving electrons around atoms. They are composed made up of positively charged anion as well as negatively charged anions. The rules for naming ionic compounds are as below:

1. Note the name of the Cation first, then the name of the anion.
2. If the cation contains more than one possible charge then indicate the charge using Roman numerals in brackets.
3. If an anion’s structure is polyatomic Ion, identify the Ion.

Examples:

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

Naming Covalent Compounds

Covalent compounds are formed by sharing electrons among atoms. They consist of molecules made comprised of two or three atoms. The guidelines for naming compounds that are covalent are as below:

1. Then write the name of first element in the formula.
2. Write“Element 2” as the title of the formula, and change the end to “-ide”.
3. Prefixes are used to indicate the amount of atoms found in every element of the molecule, except for“mono,” for example “mono-” for the first element.

Examples:

• CO2 is the name given to carbon dioxide.
• N2O is named dinitrogen monoxide.
• SHF is also known as sulfur Hexafluoride.

Naming Binary Compounds

Binary compounds are compounds made from two elements. The rules for the name of binary compounds are in the following order:

1. Note the name of first element in the formula.
2. Enter the name of the second element in the formula, changing the end“ide “-ide”.

Examples:

• The name of HCl is hydrogen cyanide.
• CO is the abbreviation for carbon monoxide.
• CaO is also known as calcium oxide.

Practice Exercises

For reinforcement of learning for students, the worksheets will include training exercises to help students name ionic components, covalent compounds including binary ones. The exercises will assist students to establish a firm understanding of 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

In completing these tests, learners will become confident in formulating chemical names and be able to apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an important concept in chemistry , and requires a thorough understanding of fundamental rules and principles for naming different types of compounds. In following the principles laid out in this worksheet and practicing using the activities included, students can be confident in naming ionic, covalent, and other binary chemicals. This knowledge is crucial for successful chemistry, and it will lay an excellent foundation for future research in the field.
