Lewis Dot Structures


Unit 2 chemistry

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.


Unit 2 chemistry

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.


Unit 2 chemistry

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.
