Unit 2 Chemistry Lewis Dot Structures
Electron Dot Diagrams • An electron dot diagramis the symbol for the element surrounded by as many dots as there are electrons in its outer energy level.
How to Write Them • The dots are written in pairs on four sides of the element symbol. • Start by writing one dot on the top of the element symbol, then work your way around adding dots to the right, bottom, and left.
How to Write Them • Add a fifth dot to the top to make a pair. Continue in this manner until you reach the number of valence electrons the element has or until there are eight dots to complete the level.
