Exploring Covalent Bonds in Chemistry
What do you already know about covalent bonds?
Learning Objective
At the end of the lesson you will be able to explain what a covalent bond is, describe how electrons are shared, and represent covalent bonds using electron dot and structural formulas.
What Is a Covalent Bond?
A covalent bond forms when two atoms share one or more pairs of electrons. This type of bond usually occurs between non-metal atoms.
Key Properties of Covalent Bonds
Electron Sharing
Covalent bonds can be strong and require energy to break.
Atoms achieve stability by sharing electrons, filling their outer shells.
Bond Strength
Covalent Bond in Hydrogen (H2)
A hydrogen molecule consists of two H atoms sharing a pair of electrons, shown using a Lewis dot diagram.
Orbital Representation
Energy level diagrams (such as 1s or 8p) can show the distribution of electrons in atoms before and after bonding.
Representing Covalent Bonds
Covalent bonds can be represented with electron dot diagrams, structural formulas, and orbital models.
Review and Reflection
Describe in your own words how a covalent bond forms and give an example. Why is electron sharing important for atoms?
