Rules For Naming Compounds Worksheet Answers

Rules For Naming Compounds Worksheet Answers – Naming compounds is a basic idea in chemistry. It involves giving a unique name to any chemical compound based on its composition. Names of chemical compound gives important information about its properties and structure. There are various kinds that chemical compounds can be found, including the ionic compound, covalent compounds along with binary and covalent compounds.

Naming Ionic Compounds

The Ionic compound is formed by an exchange of electrons among atoms. They consist with positively charged, cations and negatively charged anion. The rules of naming ionic compounds are as they are:

1. Write the name for the cation first. Then, write its name.
2. If the cation contains multiple possible charges mark the charge in Roman numerals in brackets.
3. The anion must be a polyatomic ion, refer to the name of ion.

Examples:

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

Naming Covalent Compounds

Covalent compounds form through the sharing of electrons between atoms. They are composed of molecules made by two or many atoms. The rules for naming covalent compounds are as below:

1. Inscribe the name and the first element in the formula.
2. Enter your name for the element in the formula, and change the ending in the form of “-ide”.
3. Prefixes should be used to indicate number of atoms present in every element of the molecule. This is not the case for“mono-” which indicates the number of atoms in the molecule “mono-” for the first element.

Examples:

• CO2 is the name given to carbon dioxide.
• N2O is named dinitrogen monoxide.
• SHF6 is the name given to sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are composed up of two elements. The rules for names for binary compounds are as below:

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

Examples:

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

Practice Exercises

To enhance the learning experience for students, the worksheets will include drills for naming Ionic molecules, covalent compound, also known as binary compounds. These exercises can help students build a solid 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

When they complete these activities, students will build confidence being able to identify chemical compounds and be able apply the rules to other chemical compounds.

Conclusion:

Naming compounds is a crucial idea in chemistry that requires a thorough understanding of specific rules for calling different kinds of compounds. By following the rules outlined in this worksheet and experimenting through the exercises provided, students are able to quickly identify covalent, ionic and binary compounds. This knowledge is vital to success in chemistry . It also provides an excellent foundation for future research in the field.
