Binary Covalent Compounds Worksheet Answers Explained

Table of Contents :

Binary covalent compounds play a vital role in chemistry, particularly in the way elements bond and form new substances. Understanding how to name and write the formulas for these compounds can be a bit challenging for students. This article aims to clarify the topic, particularly by using a worksheet format to help enhance learning.

What Are Binary Covalent Compounds?

Binary covalent compounds consist of two different non-metal elements that share electrons. This sharing of electrons creates a covalent bond, resulting in the formation of a stable compound. For example, carbon dioxide (CO₂) and water (H₂O) are common binary covalent compounds.

Key Characteristics of Binary Covalent Compounds:

  • Composed of two non-metal elements: These compounds involve non-metals from the periodic table.
  • Sharing of electrons: The non-metals share their valence electrons to achieve a full outer shell, adhering to the octet rule.
  • Use of prefixes in naming: Prefixes such as mono-, di-, tri-, and tetra- are used to indicate the number of atoms present in the compound.

Example of Common Binary Covalent Compounds:

Compound Chemical Formula Number of Atoms
Carbon Dioxide CO₂ 1 Carbon, 2 Oxygen
Dihydrogen Monoxide H₂O 2 Hydrogen, 1 Oxygen
Nitrogen Trifluoride NF₃ 1 Nitrogen, 3 Fluorine
Phosphorus Pentachloride PCl₅ 1 Phosphorus, 5 Chlorine

Naming Binary Covalent Compounds

When naming binary covalent compounds, it is crucial to follow specific rules to ensure clarity and accuracy. The naming convention often involves the use of prefixes to denote the number of each type of atom.

Naming Rules:

  1. Name the first element: The name of the first non-metal is taken directly from the periodic table.
  2. Use prefixes: If there is more than one atom of the first element, use a prefix.
  3. Name the second element: The name of the second non-metal must change its suffix to "-ide."
  4. Use prefixes for the second element: Similarly, apply prefixes based on the number of atoms present.

Prefixes Used in Naming:

Prefix Number of Atoms
Mono- 1
Di- 2
Tri- 3
Tetra- 4
Penta- 5
Hexa- 6
Hepta- 7
Octa- 8
Nona- 9
Deca- 10
