The ‘Names of Covalent Compounds Worksheet’ delves into the fascinating realm of covalent compounds, providing a comprehensive overview of their nomenclature. Understanding the names of covalent compounds is crucial for effective communication and comprehension in the field of chemistry.

This worksheet embarks on an exploration of the different types of covalent compounds, including binary, ternary, and polyatomic compounds, with illustrative examples to enhance understanding.

Introduction

Covalent compounds are chemical compounds formed when two or more non-metallic elements share electrons to form a stable molecule. The nomenclature of covalent compounds is a system of rules used to name these compounds based on their composition and structure.

Understanding the names of covalent compounds is important for several reasons. It allows chemists to identify and communicate about these compounds accurately. It also helps in understanding their properties and reactivity, which is crucial in various fields such as chemistry, biology, and materials science.

Types of Covalent Compounds

Binary Covalent Compounds

Binary covalent compounds are formed between two non-metallic elements. They are typically named using the prefixes “mono-“, “di-“, “tri-“, etc. to indicate the number of atoms of each element present in the molecule.

Examples:

• Carbon dioxide (CO ₂)
• Water (H ₂O)
• Ammonia (NH ₃)

Ternary Covalent Compounds

Ternary covalent compounds are formed between three non-metallic elements. They are typically named using the prefixes “mono-“, “di-“, “tri-“, etc. to indicate the number of atoms of each element present in the molecule, followed by the suffix “-ide” to indicate the presence of a non-metal.

Examples:

• Carbon tetrachloride (CCl ₄)
• Nitrogen trifluoride (NF ₃)
• Phosphorus pentachloride (PCl ₅)

Polyatomic Covalent Compounds, Names of covalent compounds worksheet

Polyatomic covalent compounds are formed between a metal and a polyatomic ion, which is a group of atoms that carries a charge. Polyatomic ions are typically named using the suffix “-ate” or “-ite” to indicate the number of oxygen atoms present in the ion.

Examples:

• Sodium chloride (NaCl)
• Potassium sulfate (K ₂SO ₄)
• Calcium carbonate (CaCO ₃)

Naming Binary Covalent Compounds

The rules for naming binary covalent compounds are as follows:

1. The first element in the name is the one that is written first in the chemical formula.
2. The second element in the name is the one that is written second in the chemical formula, and its name is modified by adding the suffix “-ide”.
3. If the first element is present in more than one atom, a prefix is added to the beginning of its name to indicate the number of atoms present. The prefixes used are “mono-“, “di-“, “tri-“, “tetra-“, “penta-“, “hexa-“, etc.
4. If the second element is present in more than one atom, a prefix is added to the beginning of its name to indicate the number of atoms present. The prefixes used are “mono-“, “di-“, “tri-“, “tetra-“, “penta-“, “hexa-“, etc.

For example, the binary covalent compound with the chemical formula CO ₂is named carbon dioxide. The first element in the name is carbon, and the second element is oxygen. The suffix “-ide” is added to the name of oxygen to indicate that it is present in more than one atom.

Naming Ternary Covalent Compounds

The rules for naming ternary covalent compounds are as follows:

1. The first element in the name is the one that is written first in the chemical formula.
2. The second element in the name is the one that is written second in the chemical formula, and its name is modified by adding the suffix “-ide”.
3. The third element in the name is the one that is written third in the chemical formula, and its name is modified by adding the suffix “-ate” or “-ite” to indicate the number of oxygen atoms present in the ion.
4. If the first element is present in more than one atom, a prefix is added to the beginning of its name to indicate the number of atoms present. The prefixes used are “mono-“, “di-“, “tri-“, “tetra-“, “penta-“, “hexa-“, etc.
5. If the second element is present in more than one atom, a prefix is added to the beginning of its name to indicate the number of atoms present. The prefixes used are “mono-“, “di-“, “tri-“, “tetra-“, “penta-“, “hexa-“, etc.
6. If the third element is present in more than one atom, a prefix is added to the beginning of its name to indicate the number of atoms present. The prefixes used are “mono-“, “di-“, “tri-“, “tetra-“, “penta-“, “hexa-“, etc.

For example, the ternary covalent compound with the chemical formula N ₂O ₅is named dinitrogen pentoxide. The first element in the name is nitrogen, the second element is oxygen, and the third element is oxygen. The suffix “-ide” is added to the name of oxygen to indicate that it is present in more than one atom, and the suffix “-ate” is added to the name of oxygen to indicate that it is present in more than one atom.
