Learn about the basics behind drawing Lewis Structures with @ItsDrDan. We will go over counting valence electrons, drawing lone pairs, single, double, and triple bonds. We will also showcase many examples including ions in this "How to Guide" Video. This video is designed with community college and high school student introductory chemistry in mind.
00:00 Illustrating Covalently Bound Molecules
02:00 First Example with Water (H2O)
02:15 First Step: Counting Valence Electrons
04:00 Second Step: Choosing the "Center of Attention"
05:00 Third Step: Draw Skeletal Structure using single bonds
05:15 4th Step: Assign all remaining valence electrons (Octet Rule)
05:40 IMPORTANT: Duet Rule for Hydrogen and Helium
07:15 2nd Example of Oxygen Gas
08:30 Uses 5th step (if needed): use double and triple bonds
10:00 3rd Example of Nitrogen Gas
12:20 HUGE TIP: Bonding Trends
13:30 4th Example of CO2
15:40 5th Example of NH3
16:56 6th Example of CHOCl
19:28 7th Example with a Negative Charge
