Naming Type 2 Compounds Worksheet

Naming Type 2 Compounds Worksheet – Naming compounds is the most fundamental concept in chemistry. It involves assigning a distinctive name to a chemical compound based on its composition. Names of compound gives important information about its properties and structures. There are various kinds of chemical compounds, including the ionic compound, covalent compounds, or binary substances.

Naming Ionic Compounds

Ionic compounds are formed through electron transfer amongst atoms. They are composed mostly of positively charged electrons as well as negatively charged anion. The rules used to name ionic compounds are as in the following order:

1. Write the name and the catalytic cation in the first place, then that of the anion.
2. If the cation is charged with multiple possible charges mark the charge in Roman numerals inside parentheses.
3. When the anion has a polyatomic ion select the name of the Ion.

Examples:

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

Naming Covalent Compounds

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

1. Write the name for the first element of the formula.
2. Enter the name of the second element in the formula, and change the end in the form of “-ide”.
3. Use prefixes to identify the number of atoms in every element of the molecule. However, there is no need for“mono,” for example “mono-” for the first element.

Examples:

• CO2 is the name given to carbon dioxide.
• N2O is named dinitrogen monoxide.
• This is known as sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are compounds made from two elements. The rules for using the term binary compound are as the following:

1. Then write the name of 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:

• HCl is named hydrogen chloride.
• CO is named carbon monoxide.
• Calcium oxide is known as CaO.

Practice Exercises

To strengthen the understanding to reinforce the learning, the worksheet will contain examples of how to name ionic chemicals, compound covalent and binary compounds. The exercises will assist students to improve their understanding of the rules to name 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 improve their confidence formulating chemical names and be able apply the rules to other compounds.

Conclusion:

Naming compounds is a crucial aspect of chemistry that requires an understanding of fundamental rules and principles for calling different kinds of compounds. By adhering to the guidelines set forth in this worksheet, and working using the activities included, students can confidently identify ionic and covalent as well as binary substances. This knowledge is vital to success in chemistry and lays an excellent foundation for future research in the field.
