Naming Compounds And Molar Masses Worksheet

Naming Compounds And Molar Masses Worksheet – Naming of compounds is a fundamental concept in chemical science. It involves the assignment of a unique name to an chemical compound, based on its composition. Names of compound provides important information about its properties and structures. There are different types of chemical compounds. These include covalent compounds, ionic compounds, also known as binary compounds.

Naming Ionic Compounds

Ionic compounds are formed through electron transfer between electrons. They consist of positively charged cations and negatively charged anion. The rules of naming ionic compounds are as like this:

1. Inscribe the name of an atom first, followed by the name of the anion.
2. If the cation may have more than one charge then indicate the charge using Roman numbers in parentheses.
3. If an anion’s structure is polyatomic ion, you should use the name given to the Ion.

Examples:

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

Naming Covalent Compounds

Compounds that are covalent are formed through the sharing of electrons among atoms. They are composed of molecules made comprised of two or three atoms. The rules for naming covalent compounds are as these:

1. Write the name for the first element of the formula.
2. Enter in the first element’s name of the formula, and change the ending in the form of “-ide”.
3. Use prefixes for the amount of atoms found in every element of the molecular structure, except for using the suffix “mono-” for the first element.

Examples:

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

Naming Binary Compounds

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

1. Name the first element in the formula.
2. Enter the name of the second element of the formula, and change the ending in the form of “-ide”.

Examples:

• Hydrogen chloride is the name given to it.
• CO is named carbon monoxide.
• CaO is also known as calcium oxide.

Practice Exercises

For reinforcement of learning it will be accompanied by the practice of naming ionic compound, compounds with covalent bonds, or binary substances. The exercises will help students develop a solid understanding of the principles 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

As they complete these exercises students will improve their confidence making chemical compounds known and be able to apply these rules to other compounds.

Conclusion:

Naming compounds is a crucial concept in chemistry that requires an understanding of the rules and guidelines to making names for various kinds of compounds. By adhering to the guidelines set forth in this worksheet and experimenting with the included exercises students can successfully identify ionic, chemical also binary compounds. This is vital for being successful in chemistry. It provides the foundation for further studies in the field.
