Lew dot diagrams are a simplified way to show how the electrons are arrnaged in their outer energy level.  This is where the chemical reactions take kplace.  Dots are placed around the element sysmbol in the following way.
 

Step One	Step Two	Step Three	Step Four
Step Five	Step Six	Step Seven	Step Eight

 

Draw the Lewis Dot Diagrams for elements 1-18.
