Naming Worksheet 2 Naming Molecular Compounds

Naming Worksheet 2 Naming Molecular Compounds – Naming chemical compounds is an essential idea in chemistry. It involves assigning a unique name to one chemical substance based on its composition. In addition, the name assigned to the chemical compound contains important information about the properties and structure of the compound. There are different types of chemical compounds. These include the ionic compound, covalent compounds the binary type of compounds.

Naming Ionic Compounds

Ionic compounds are created by an exchange of electrons among atoms. They consist with positively charged, cations as well as negatively charged anion. The criteria for naming ionic compounds are as below:

1. Inscribe the name of cation first, followed by your name and the name of the anion.
2. If the cation may have multiple possible charges, indicate the charge using Roman numerals in brackets.
3. If there is a possibility of polyatomic ion, use the name of the ion.

Examples:

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

Naming Covalent Compounds

Covalent compounds are made by the sharing of electrons between atoms. They consist of molecules that are made comprised of two or three atoms. The guidelines for naming covalent compounds are as below:

1. Write the name of the first element in the formula.
2. Enter“ide” in place of “ide” in the formula, changing the ending“ide “-ide”.
3. Prefixes should be used to indicate amount of atoms found in each element in the molecule, except for“mono,” for example “mono-” for the first element.

Examples:

• CO2 is also known as carbon dioxide.
• N2O is named dinitrogen monoxide.
• So, SF6 is a sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are those made from two elements. The rules for the naming of binary compounds are as they are:

1. Write the name and the first element of the formula.
2. Enter in the first element’s name in the formula, and change the ending“-ide. “-ide”.

Examples:

• The name of HCl is hydrogen cyanide.
• CO is a chemical compound known as carbon monoxide.
• CaO is named calcium oxide.

Practice Exercises

To further reinforce the learning for students, the worksheets will include practice exercises for naming ionic substances, chemical compounds that are covalent in addition to binary compounds. This will help students get a better understanding of the rules 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

In completing these tests, students will gain confidence in being able to identify chemical compounds and be able to apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an essential concept in chemistry . It requires an understanding of fundamental rules and principles to names for different kinds of compounds. When following the guidelines provided in this worksheet and experimenting through the exercises provided, students will be able effectively identify covalent, ionic as well as binary substances. This knowledge is crucial for success in chemistry and lays solid foundations for further studies in the area.
