THURSDAY - 3/19/20 - DRAWING LEWIS STRUCTURES -  

 

Today you will be writing down how to draw Lewis Structures by writing down the rules and watching a few examples on YouTube.

 

1 - Create the heading "How to Draw Lewis Structures" and copy down the following steps.

   

   1. Find the total number of electrons in the compound.

   2. The central atom is the least electronegative, excluding H because it can only make one bond.

   3. Connect the other atoms to the central atom using a single bond.

   4. Count each single bond as a pait (two) electrons.

   5. Add electrons to the outer atoms to give each one 8, a full electron shell. 

   6. Do the same for the central atom.

   7. Check: Does each atoms have a full outer shell?

 

 

2 - Next, watch the following video on Lewis Structures - https://www.youtube.com/watch?v=Sk7W2VgbhOg
