Naming Chemical Compounds Worksheet Answer Key

Naming Chemical Compounds Worksheet Answer Key – Naming compounds is an important concept in the field of chemistry. It involves giving a unique name to any chemical compound based on its composition. The name of a chemical compound will provide crucial information about the properties and structure of the compound. There are various kinds of chemical compounds. They include the ionic compound, covalent compounds, in addition to binary ones.

Naming Ionic Compounds

Ionic compounds can be formed by electron transfer across the atom. They are composed made up of positively charged anion and negatively charged anions. The rules to name ionic compounds are as follows:

1. Write the name of the compound first, and then your name and the name of the anion.
2. If the cation has multiple possible charges mark the charge in Roman numerals that are enclosed in parentheses.
3. When the anion has a polyatomic ion take the name of that ion.

Examples:

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

Naming Covalent Compounds

The formation of covalent compounds is caused by the sharing of electrons among atoms. They are composed of molecules made up of two or more atoms. The guidelines for naming compounds that are covalent are as they are:

1. Inscribe the name and the first element of the formula.
2. Enter“name” of second component in the formula, and change the ending“-ide “-ide”.
3. Prefixes indicate the number of atoms for every element of the molecule. There is no prefix for“mono-” which indicates the number of atoms in the molecule “mono-” for the first element.

Examples:

• CO2 is a carbon dioxide derived name.
• N2O is named dinitrogen monoxide.
• So, SF6 is a sulfur hexafluoride.

Naming Binary Compounds

Binary compounds are those made of two components. The rules for names for binary compounds are as below:

1. Write the name for the first element in the formula.
2. Write“Name” for second element in the formula, changing the ending in the form of “-ide”.

Examples:

• The name HCl refers to hydrogen chloride.
• CO is the scientific name for carbon monoxide.
• CaO is a name for calcium oxide.

Practice Exercises

To aid in learning in the classroom, the worksheet contains practice exercises for naming ionic chemicals, compound covalent or binary substances. These activities will help students gain a thorough 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

By completing these exercises, students will improve their confidence formulating chemical names and be able apply the rules to other chemical compounds.

Conclusion:

Naming compounds is an essential notion in chemistry and requires a deep understanding of principles and regulations to names for different kinds of compounds. Following the guidelines laid out in this worksheet, and working by using the included exercises, students are able to easily identify ionic, covalent and binary compounds. This skill is essential to the success of chemistry and provides the foundation for further studies in the area.
