How to draw Lewis Structures - Real Chemistry
In this video you will learn how to draw lewis structures for simple molecules. This involves determining the number of bonds needed for each atom. For hydrogen, this is 1, for carbon, 4, for nitrogen, 3, for oxygen 2, and for all of the halogens, 1. Next guess the structure, usually the atom with the most bonds should go in the center. Use single, double, or triple bonds as needed to fulfill the correct number of bonds for each atom. Then add lone pairs to each atom to get an octet, remembering that hydrogen needs only 2 electrons. Finally check to ensure you have the correct number of valence electrons.
Bonding: Part 4, Lewis Structure Practice
Here we practice drawing Lewis structures. We include polyatomic ions as well as multiple bonds. We also discuss molecular shape.
Bonding: Introduction to Lewis Dot Structures
The great chemist, Gilbert N. Lewis created a simple way to show how atoms in compounds (typically covalent) bond with each other. The trick to keeping it simple was to focus only on showing valence electron interactions. This video will show you the trick to writing Lewis (Dot) Structures correctly.

Lewis Structures of Ions - Mr Pauller
This video demonstrates how to write Lewis structures for monoatomic and polyatomic ions.
Lewis Structures for Beginners
In this video we will learn how to draw the lewis structures of single atoms and beginning level molecules containing all single bonds.

I post so many different videos on YouTube sometimes finding the one you want can be frustrating and confusing.
This video is about Lewis Structures, and discusses in details the method of drawing lewis structures for molecules, ions and ionic compounds. In this video I discuss the following examples of drawing Lewis structure: - Water: H2O. - Carbon dioxide: CO2. - Triiodide: I3-. - Sulfate: SO42- - And several other examples. Moreover, the exceptions to the octet rule were discussed in addition to determining the major contributor to the Lewis structure using the formal charges. Students studying Chemistry at different levels could highly benefit from this video.
