How to Draw Lewis Structures

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
