Naming Molecular Compounds Worksheets

Naming Molecular Compounds Worksheets – Naming of compounds is a fundamental concept in chemical science. It involves assigning an unique name to the chemical compound on the basis of its composition. Names of compound is a crucial indicator of its properties as well as its structure. There are different types of chemical compounds. They include covalent compounds, ionic compounds along with binary and covalent compounds.

Naming Ionic Compounds

Ionic compounds arise from an exchange of electrons among atoms. They are made up made up of positively charged anion as well as negatively charged anion. The criteria for naming ionic compounds are as the following:

1. Enter the name of the an atom first, followed by the name of the anion.
2. If the cation has multiple possible charges make sure to indicate the charge with Roman numerals in parentheses.
3. If the anion is a polyatomic ion, select the name of the ion.

Examples:

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

Naming Covalent Compounds

Covalent compounds are created through sharing electrons among atoms. They are composed of molecules made comprising two or more atoms. The guidelines for naming compounds that are covalent are as follows:

1. Write the name for the first element in the formula.
2. Write the name of the second element of the formula, changing the end“-ide. “-ide”.
3. Prefixes are used to indicate the quantity of atoms contained in every element of the molecule. There is no prefix for“mono” as a prefix “mono-” for the first element.

Examples:

• Carbon dioxide is the name of CO2.
• 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 names of binary compounds can be described as they are:

1. Then write the name of first element of the formula.
2. Enter the name of the second element in the formula, and change the end to “-ide”.

Examples:

• The name of HCl is hydrogen cyanide.
• CO is known as carbon monoxide.
• Calcium oxide is also known as.

Practice Exercises

To further reinforce the learning this worksheet will offer training exercises to help students name ionic and covalent substances and binary compounds. This will help students improve their 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

When they complete these activities, students will become more confident in formulating chemical names and be able apply the rules to other compounds.

Conclusion:

Naming compounds is a crucial idea in chemistry. It requires a good understanding of fundamental rules and principles for making names for various kinds of compounds. By adhering to the guidelines set forth in this worksheet and experimenting by using the included exercises, students can effectively identify covalent, ionic in addition to binary, compounds. This is a must for success in chemistry . It also provides solid foundations for further studies in the field.
