Naming Molecular Compounds Chem Worksheet 9 2

Naming Molecular Compounds Chem Worksheet 9 2 – Naming compounds is the most fundamental concept in chemistry. It involves giving a unique name to an chemical compound, based on its composition. When you name a chemical compound provides important information about its properties and structures. There are several kinds of chemical compounds, such as chemical compounds that are ionic, covalent, and binary compounds.

Naming Ionic Compounds

Ionic compounds are produced by the transfer of electrons between atoms. They are made up comprise positively charged Cations as well as negatively charged anion. The rules for naming ionic compounds are as according to:

1. The name of the initial cation, followed by an anion’s name.
2. If the cation contains more than one charge Indicate the charge with Roman numerals that are enclosed in parentheses.
3. In the case of a multiatomic ion choose the name of the Ion.

Examples:

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

Naming Covalent Compounds

Covalent compounds are made by sharing electrons among atoms. They consist of molecules made comprised of two or three atoms. The rules for naming covalent compounds are as according to:

1. Inscribe the name of the first element of the formula.
2. Write“ide” in place of “ide” of the formula, and change the end“-ide. “-ide”.
3. Prefixes can be used to indicate the amount of atoms that make up each element in the molecule. The exception is“mono,” for example “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 consist from two elements. The rules for names of binary compounds can be described as below:

1. Enter the name of the first element of the formula.
2. Write“Name” for second element in the formula, changing the end to “-ide”.

Examples:

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

Practice Exercises

For reinforcement of learning, the worksheet will include practices for naming ionic and covalent substances, as well as binary compound. These exercises will aid students develop a solid understanding of how 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

When they complete these activities, students will gain confidence in formulating chemical names and be able to apply these rules to other compounds.

Conclusion:

Naming compounds is a crucial concept in the field of chemistry. It requires a solid understanding of how to follow the guidelines and rules for creating names for different kinds and types of compounds. In following the principles laid out in this worksheet and practicing with the included exercises students can confidently identify ionic and covalent, in addition to binary, compounds. This is vital for success in chemistry . It also provides an excellent foundation for future research in the area.
