Naming Simple Molecular Compounds Worksheet

Naming Simple Molecular Compounds Worksheet – Naming compounds is a key idea in chemistry. It involves assigning a distinctive name to the chemical compound on the basis of its composition. It is important to know that the name given to a compound offers important information on its properties and its structure. There are various types of chemical compounds, such as organic compounds, covalent ones, also known as binary compounds.

Naming Ionic Compounds

Ionic compounds are created by an exchange of electrons among atoms. They are made up of negatively charged cations and negatively charged anions. The rules to name ionic compounds are as they are:

1. Write the name of the cation first, followed by it’s anion’s name.
2. If the cation could have more than one possible charge Indicate the charge with Roman numbers enclosed in parentheses.
3. When the anion has a polyatomic ion, make use of the name for the anion.

Examples:

• NaCl is a name for sodium chloride.
• FeCl3 is named iron(III) chloride.
• Mg(NO3)2 is known as magnesium nitrate.

Naming Covalent Compounds

Covalent compounds arise from the sharing of electrons between atoms. They consist of molecules made by two or more atoms. The guidelines for naming covalent compounds are as like this:

1. Note the name of first element of the formula.
2. Write“ide” in place of “ide” of the formula, changing the end“-ide “-ide”.
3. Prefixes indicate the number of atoms present in each element in the molecule, except for the prefix “mono-” for the first element.

Examples:

• CO2 is also known as carbon dioxide.
• N2O is named dinitrogen monoxide.
• The name SF6 refers to sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are substances made by two elements. The rules for the name of binary compounds are they are:

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

Examples:

• It is known as hydrogen chloride.
• CO is also known as carbon monoxide.
• The name CaO comes from calcium oxide.

Practice Exercises

To further reinforce the learning in the classroom, the worksheet contains activities for practicing naming ionic compound, compounds with covalent bonds, as well as binary compound. These exercises will help students build a solid understanding of the rules 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

By completing these exercises, students will become more confident in being able to identify chemical compounds and be able to apply these rules to other chemical compounds.

Conclusion:

Naming compounds is a crucial idea in chemistry that needs a solid understanding what rules apply and the best practices for making names for various kinds of compounds. Through following the steps laid out in this worksheet and experimenting with the included exercises students can confidently name ionic, covalent, the binary chemical compounds. This is vital for success in chemistry and lays the foundation for further studies in the area.
