Naming Molecular Compounds And Writing Molecular Formulas Worksheet

Naming Molecular Compounds And Writing Molecular Formulas Worksheet – Naming compounds is a basic idea in chemistry. It involves granting a unique name to each chemical compound according to its composition. It is important to know that the name given to a chemical compound is a crucial indicator of the properties and structure of the compound. There are several kinds that chemical compounds can be found, including the ionic compound, covalent compounds the binary type of compounds.

Naming Ionic Compounds

Ionic compounds are created by electron transfer across the atom. They consist from positively charged cations and negatively charged anion. The rules to name ionic compounds are as they are:

1. Note the name of the cation first, followed by your name and the name of the anion.
2. If the cation is charged with multiple possible charges, indicate the charge using Roman numerals in brackets.
3. When the anion has a polyatomic ion, make use of the name for the anion.

Examples:

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

Naming Covalent Compounds

Covalent compounds are made by the sharing of electrons between atoms. They are composed of molecules made consisting of two or even more atoms. The guidelines for naming covalent compounds are as the following:

1. Note the name of first element in the formula.
2. Write“the name” for the 2nd element in the formula, and change the end“ide “-ide”.
3. Prefixes should be used to indicate amount of atoms found in every element of the molecule. The exception is“mono-” for the first element “mono-” for the first element.

Examples:

• CO2 is a carbon dioxide derived name.
• N2O is named dinitrogen monoxide.
• The name SF6 refers to sulfur hexafluoride.

Naming Binary Compounds

Binary compounds consist by two elements. The rules for using the term binary compound are as like:

1. Name the first element of the formula.
2. Write an appropriate name for each element in the formula, and change the ending to “-ide”.

Examples:

• Hydrogen chloride is the name given to it.
• CO is the name given to carbon monoxide.
• The name CaO comes from calcium oxide.

Practice Exercises

For reinforcement of learning and reinforce learning, the worksheet includes activities for practicing naming ionic elements, covalent components in addition to binary compounds. These activities will help students improve their understanding of the rules for 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

By completing these exercises, students will improve their confidence formulating chemical names and be able to apply these rules to other compounds.

Conclusion:

Naming compounds is a crucial idea in chemistry that requires a solid understanding of the rules and guidelines for giving different compounds different names. Through following the steps laid out in this worksheet and experimenting with the included activities, students can quickly identify covalent, ionic, as well as binary substances. The knowledge gained is essential for successful chemistry, and it will lay the foundation for future research in the field.
