Writing And Naming Molecular Compounds Worksheet

Writing And Naming Molecular Compounds Worksheet – Naming compounds is an essential idea in chemical science. It involves assigning a unique name to compounds based upon its composition. What is the title of a compound contains important information about its properties and structures. There are different kinds of chemical compounds, including those with ionic properties, covalent compound the binary type of compounds.

Naming Ionic Compounds

The Ionic compound is formed by moving electrons around atoms. They are made up comprise positively charged Cations as well as negatively charged anions. The criteria for naming ionic compounds are as follows:

1. Inscribe the name of initial cation, followed by its name.
2. If the cation contains multiple possible charges be sure to identify the charge using Roman numerals inside parentheses.
3. For anion that is not a polyatomic Ion, take the name of that ion.

Examples:

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

Naming Covalent Compounds

Covalent compounds are formed by sharing electrons among atoms. They consist of molecules that are made consisting of two or even more atoms. The rules for naming compounds that are covalent are as these:

1. Inscribe the name of the first element in the formula.
2. Write the name of the second element in the formula, changing the end in the form of “-ide”.
3. Use prefixes to indicate the number of elements in every element of the molecule. Except for the prefix “mono-” for the first element.

Examples:

• Carbon dioxide is the name of CO2.
• N2O is named dinitrogen monoxide.
• SHF6 is the name given to sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are substances made up of two elements. The rules for names of binary compounds can be described as the following:

1. Then write the name of first element in the formula.
2. Write an appropriate name for each element in the formula, changing the ending“-ide. “-ide”.

Examples:

• The name HCl refers to hydrogen chloride.
• CO is a chemical compound known as carbon monoxide.
• CaO is the name given to calcium oxide.

Practice Exercises

To enhance the learning experience to reinforce the learning, the worksheet will contain the practice of naming ionic compound, compounds with covalent bonds,, and other binary chemicals. The exercises 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

As they complete these exercises learners will become confident in the identification of chemical compounds, and will be able to apply these rules to other chemical compounds.

Conclusion:

Naming compounds is an essential concept in the field of chemistry. It requires a good understanding of basic rules and procedures for making names for various kinds of compounds. If you follow the rules laid out in this worksheet, and working using the exercises included, students will be able effectively identify covalent, ionic in addition to binary, compounds. The knowledge gained is essential for the success of chemistry and provides solid foundations for further studies in the field.
