This is a Videoscribe tutorial on how to draw Lewis structures of molecules. This is my second tutorial in the series. The first video includes Lewis diagrams of atoms and can be found here: https://youtu.be/cIuXl7o6mAw Lewis diagrams (aka Lewis structures, Lewis dot structures, Lewis dot diagrams) are useful because they use simple drawings to show how atoms share valence electrons in molecules, polyatomic ions, and other covalent structures. This video: 1) reviews the 5 basic steps for creating a Lewis structure 2) goes through 4 detailed examples 3) identifies patterns of bonding to help create Lewis structures 4) introduces a faster way to draw Lewis structures 5) demonstrates how this trick works or falls short for 4 additional detailed examples

To see all my Chemistry videos, check out http://socratic.org/chemistry Here's how to write formulas for ionic compounds that contain polyatomic ions. In order to write formulas for polyatomic ions, you have to look at a chart or table of polyatomic ions to find out what the charge of each one is. Then, you figure out how many other ions will be necessary to balance out the charges and make it neutral.
"Can a broken nut can be fixed with baking soda and super glue?" Lou, a singer here in Athens, Ohio, brought this question to Dan Erlewine (along with the broken nut on his Yamaha guitar). As it turns out, the answer is yes and no...

A step-by-step explanation of how to draw the Ag2O Lewis Dot Structure.
For Ag2O we have an ionic compound and we need to take that into account when we draw the Lewis Structure. We’ll first draw the metal and put it in brackets with its charge on the outside (video: finding ionic charge: https://youtu.be/M22YQ1hHhEY).
Next, we'll draw the Lewis Structure for the O2- ion and add brackets. We put the two ions together to complete the Lewis structure for Ag2O. Note that Ag2O is also called Silver (I) oxide.
For a complete tutorial on drawing Lewis Structures, see my video: https://youtu.be/1ZlnzyHahvo

To learn to find the valence electrons: https://youtu.be/VBp7mKdcrDk
Note that is it more common to draw Lewis Structures for covalent (molecular) compounds where valance electrons are shared. In the case of ionic compounds, where we have a metal bonded to a non-metal (or group of non-metals), the Lewis diagram represents a formula unit. Many of these formula units make up a crystal lattice. So when we talk about the structure for Ag2O we think of it together with other Ag2O formula units in a crystal (NaCl is a good example of this: https://en.wikipedia.org/wiki/Sodium_chloride).
