In this lesson, we learn how to draw Lewis structures (electron dot structures) to represent how valence electrons are arranged in covalent compounds.
You’ll learn:
• How to determine the total number of valence electrons
• How to choose the correct central atom
• How to draw single, double, and triple bonds
• How to account for lone pairs
• How to check your electron count
• The seven diatomic elements to remember
We’ll walk step-by-step through the process of drawing simple Lewis structures and discuss what to do when you end up with unpaired electrons. By the end of this lesson, you’ll be able to confidently draw Lewis structures for common molecules and understand how they represent shared electrons in covalent bonding.
This lesson builds the foundation for molecular geometry, polarity, and hybridization — so mastering these steps is essential!
