Naming Compounds Worksheet With Key Docx

Naming Compounds Worksheet With Key Docx – Naming compounds is the most fundamental idea in the field of chemistry. It involves the assignment of a unique name to any chemical compound based on its composition. Names of chemical compound offers important information on its properties and its structure. There are different kinds of chemical compounds, including the ionic compound, covalent compounds, as well as binary compound.

Naming Ionic Compounds

Ionic compounds form through electron transfer between electrons. They are composed of negatively charged cations and negatively charged anion. The rules of naming ionic compounds are as according to:

1. Inscribe the name of cation first. Then, write its name.
2. If the cation is charged with more than one possible charge, indicate the charge using Roman numerals in brackets.
3. If an anion’s structure is polyatomic Ion, choose the name of the Ion.

Examples:

• NaCl is named 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 exchange of electrons between atoms. They are made up of molecules composed by two or many atoms. The rules for naming compounds that are covalent are as below:

1. Note the name of first element in the formula.
2. Write your name for the element in the formula, and change the ending“-ide “-ide”.
3. Prefixes are used to indicate the number of atoms present in every element of the molecule. There is no prefix for using the suffix “mono-” for the first element.

Examples:

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

Naming Binary Compounds

Binary compounds are those made up of two elements. The rules for choosing the proper name for binary compounds is as in the following order:

1. Inscribe the name of the first element of the formula.
2. Enter“double element” in the formula, and change the end to “-ide”.

Examples:

• Hydrogen chloride is also known as hydrogen.
• CO is named carbon monoxide.
• CaO is a name for calcium oxide.

Practice Exercises

To further reinforce the learning, the worksheet will include practice exercises for naming ionic elements, covalent components, or binary substances. This will help students gain a thorough 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

As they complete these exercises learners will become confident in being able to identify chemical compounds and be able to apply the rules to other compounds.

Conclusion:

Naming compounds is an essential concept in chemistry , and requires a deep understanding of what rules apply and the best practices for the naming of different kinds of compounds. By adhering to the guidelines set forth in this worksheet, and working using the exercises included, students can confidently identify ionic and covalent along with binary and covalent compounds. This is vital for achievement in chemistry. It will also provide the foundation for further studies in the field.
