Practice Lewis Structure in Chemistry
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A diagram showing atoms, bonds, and lone pairs of electrons in a molecule, following the octet rule.
A map showing how electrons are arranged and shared between atoms.
Example 1
easyDraw the Lewis structure for water (\text{H}_2\text{O}).
Example 2
mediumDraw the Lewis structure for carbon dioxide (\text{CO}_2).
Example 3
hardDraw the Lewis structure for the nitrate ion (\text{NO}_3^-). Include formal charges.
Example 4
mediumDraw the Lewis structure for ammonia (\text{NH}_3), and state how many lone pairs are on the nitrogen atom.
