Worksheet Writing Chemical Formulas And Naming Compounds Answers

Worksheet Writing Chemical Formulas And Naming Compounds Answers – Naming compounds is an important concept in chemical science. It involves granting a unique name to compounds based upon its composition. In addition, the name assigned to the compound is a crucial indicator of its properties and structure. There are many types that chemical compounds can be found, including organic compounds, covalent ones or binary substances.

Naming Ionic Compounds

Ionic compounds are produced by the transfer of electrons between atoms. They are composed from positively charged cations as well as negatively charged anion. The rules for naming ionic compounds are as the following:

1. Write the name for the Cation first, then its name.
2. If the cation is charged with more than one charge then indicate the charge using Roman numbers enclosed in parentheses.
3. If it is a polyatomic ion choose the name of the anion.

Examples:

• NaCl is the name given to sodium chloride.
• FeCl3 is known as iron(III) chloride.
• Mg(NO3)2 is known as magnesium nurate.

Naming Covalent Compounds

They are created by sharing electrons among atoms. They consist of molecules that are made consisting of two or more atoms. The rules for naming compounds that are covalent are as in the following order:

1. Write the name of the first element of the formula.
2. Write the name of the second element in the formula, changing the ending“-ide. “-ide”.
3. Utilize prefixes to represent the number of atoms present in every element of the molecule. However, there is no need for“mono-,” the particular prefix “mono-” for the first element.

Examples:

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

Naming Binary Compounds

Binary compounds are the ones made up of two elements. The rules for naming binary compounds are as they are:

1. Inscribe the name of the first element in the formula.
2. Enter the name of the second element in the formula, changing the ending to “-ide”.

Examples:

• The name HCl refers to hydrogen chloride.
• CO is also known as carbon monoxide.
• Calcium oxide is also known as.

Practice Exercises

In order to reinforce the learning process to reinforce the learning, the worksheet will contain an exercise to practice naming ionic elements, covalent components, or binary substances. This will help students achieve a good understanding of the rules used 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

If they can complete these assignments, students will have confidence the identification of chemical compounds, and will be able to apply these rules to other compounds.

Conclusion:

Naming compounds is a crucial concept in the field of chemistry. It requires a good understanding of how to follow the guidelines and rules to calling different kinds of compounds. In following the principles laid out in this worksheet, and working with the included exercises students will be able quickly identify covalent, ionic the binary chemical compounds. This is a must for achievement in chemistry. It will also provide the foundation for further research in the field.
