Writing Chemical Formulas And Naming Compounds Worksheet

Writing Chemical Formulas And Naming Compounds Worksheet – Naming compounds is a key idea in chemical science. It involves assigning a distinctive name to one chemical substance based on its composition. Names of chemical compound provides important information about its properties and its structure. There are different kinds of chemical compounds. They include the ionic compound, covalent compounds, the binary type of compounds.

Naming Ionic Compounds

Ionic compounds arise from electron transfer across the atom. They are composed from positively charged cations and negatively charged anions. The rules of naming ionic compounds are as the following:

1. Write the name of initial cation, followed by the name of the anion.
2. If the cation contains more than one charge make sure to indicate the charge with Roman numbers in parentheses.
3. For anion that is not a polyatomic Ion, take the name of that Ion.

Examples:

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

Naming Covalent Compounds

Covalent compounds are created through sharing electrons among atoms. They consist of molecules made consisting of two or even more atoms. The guidelines for naming covalent compounds are as according to:

1. Inscribe the name and the first element in the formula.
2. Enter“Element 2” as the title in the formula, changing the end“-ide” to “-ide”.
3. Use prefixes to indicate the number of atoms present in each element in the molecule, with“mono-” which indicates the number of atoms in the molecule “mono-” for the first element.

Examples:

• CO2 is also known as carbon dioxide.
• N2O is named dinitrogen monoxide.
• It is also known as sulfur hexafluoride.

Naming Binary Compounds

Compounds that are binary are those made of two components. The rules for using the term binary compound are as like:

1. Write the name of the first element of the formula.
2. Enter“I” as the title of your second ingredient of the formula, changing the end“-ide” to “-ide”.

Examples:

• Hydrogen chloride is also known as hydrogen.
• CO is the scientific name for carbon monoxide.
• The name CaO comes from calcium oxide.

Practice Exercises

To enhance the learning experience and reinforce learning, the worksheet includes an exercise to practice naming ionic compounds, covalent compounds or binary substances. These exercises will help students achieve a good understanding of the rules of 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

By completing these exercises, students will have confidence understanding chemical compound names and be able to apply the rules to other compounds.

Conclusion:

Naming compounds is an essential notion in chemistry and requires a deep understanding of what rules apply and the best practices to the naming of different kinds of compounds. In following the principles laid out in this worksheet and practicing through the exercises provided, students will be able effectively identify covalent, ionic and binary compounds. This knowledge is crucial for success in chemistry . It also provides the foundation for future research in the field.
