Writing Formulas And Naming Compounds Worksheet Section 3

Writing Formulas And Naming Compounds Worksheet Section 3 – Naming compounds is an important idea in the field of chemistry. It involves assigning a distinctive name to compounds based upon its composition. When you name a compound gives important information about its properties and structures. There are various kinds of chemical compounds. This includes ionic compounds, covalent compounds, the binary type of compounds.

Naming Ionic Compounds

Ionic compounds are formed through transfers of electrons across atoms. They are made up in positively charged caustics as well as negatively charged anions. The guidelines for naming ionic compounds are as these:

1. Write the name for the compound first, and then your name and the name of the anion.
2. If the cation may have multiple possible charges Indicate the charge with Roman numbers in parentheses.
3. If an anion’s structure is 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 known under the name magnesium nitrate.

Naming Covalent Compounds

The formation of covalent compounds is caused by the sharing of electrons among atoms. They consist of molecules made comprising two or more atoms. The rules for naming covalent compounds are as like this:

1. Write the name of the first element of the formula.
2. Write your name for the element in the formula, and change the ending to “-ide”.
3. Utilize prefixes to represent the number of elements in every element of the molecular structure, except for using the suffix “mono-” for the first element.

Examples:

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

Naming Binary Compounds

Compounds that are binary are those made up of two elements. The rules for choosing the proper name for binary compounds is as these:

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

Examples:

• Hydrogen chloride is the name given to it.
• CO is named carbon monoxide.
• The name CaO comes from calcium oxide.

Practice Exercises

In order to reinforce the learning process it will be accompanied by training exercises to help students name ionic compounds, covalent compounds as well as binary compound. These exercises will help students develop a solid understanding of the rules that govern the naming of 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

If they can complete these assignments, students will have confidence making chemical compounds known and be able to apply these rules to other chemical compounds.

Conclusion:

Naming compounds is an essential aspect of chemistry that requires a solid understanding of what rules apply and the best practices for naming different types of compounds. Following the guidelines outlined in this worksheet and practicing with the included exercises students are able to effectively identify covalent, ionic, or binary compound. This knowledge is crucial for being successful in chemistry. It provides an excellent foundation for future studies in the area.
