Lewis and Electron Dot Diagrams

Okay, most of you know the Bohr Model... right? Well Lewis models are sort of like Bohr Models but with only the valence electrons around them.
Valence electrons are.... Electrons in the outermost shell of an element or atom. Also called the "reactable electrons."
Sometimes Lewis diagrams are called dot structures because the diagram is made of dots, obviously.
So how do you draw a Lewis/ Dot Diagram?
Step One - What element are you drawing?? Count the electrons.
Step Two - Place the valence electrons around the element symbol.
