Naming Molecular Compounds Worksheet Model 1 Molecular Compounds

Naming Molecular Compounds Worksheet Model 1 Molecular Compounds – Naming compounds is an essential concept in chemistry. It involves assigning an unique name to an chemical compound, based on its composition. It is important to know that the name given to a chemical compound will provide crucial information about its properties and the structure. There are several kinds of chemical compounds. These include covalent compounds, ionic compounds,, and even binary compounds.

Naming Ionic Compounds

Ionic compounds are created by transfers of electrons across atoms. They are composed mostly of positively charged electrons as well as negatively charged anions. The rules for naming Ionic compounds are as according to:

1. Inscribe the name of compound first, and then it’s anion’s name.
2. If the cation may have more than one charge Indicate the charge using Roman numerals in brackets.
3. If an anion’s structure is polyatomic ion you should use the name given to the Ion.

Examples:

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

Naming Covalent Compounds

Covalent compounds form through the sharing of electrons between atoms. They are made up of molecules composed comprised of two or three atoms. The rules for naming compounds that are covalent are as the following:

1. Write the name for the first element in the formula.
2. Write an appropriate name for each element of the formula, and change the ending“-ide “-ide”.
3. Use prefixes for the number of atoms for each element in the molecule, except for“mono” as a prefix “mono-” for the first element.

Examples:

• CO2 is the name given to carbon dioxide.
• N2O is named dinitrogen monoxide.
• The term SF6 stands for sulfur hexafluoride.

Naming Binary Compounds

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

1. Write the name of the first element of the formula.
2. Enter an appropriate name for each element of the formula, and change the end in the form of “-ide”.

Examples:

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

Practice Exercises

To aid in learning to reinforce the learning, the worksheet will contain activities for practicing naming ionic components, covalent compounds, as well as binary compound. These exercises will allow students to develop a solid understanding of the rules used to name chemical compounds.

Ionic Compound Naming Exercises:

1. Na2S
2. KBr
3. CaF2
4. Al2O3

Covalent Compound Naming Exercises:

4. NO

Through these exercises, students will gain confidence in understanding chemical compound names and be able to apply these rules to other chemical compounds.

Conclusion:

Naming compounds is an important notion in chemistry and requires an understanding of fundamental rules and principles for Naming different kinds of compounds. Through following the steps laid out in this worksheet and practicing by using the included exercises, students will be able to be confident in naming ionic, covalent also binary compounds. This information is crucial to the success of chemistry and provides solid foundations for further research in the field.
