Lewis Dot Structures for Covalent Compounds Part 1 This awesome video shows how to draw lewis dot structures for covalent compounds. Step by step instruction is provided on how to draw these molecular lewis dot structures. In order to fully understand this video, you'll need to know how to determine the number of valance electrons an element has. You'll find that these molecules also have single, double and triple covalent bonds.Thanks for tuning in. Peace.
