Lewis Dot Diagrams (symbols)

Lewis Dot Diagrams are symbolic representations of the valence electrons in an atom and are also known as electron dot diagrams.

Lewis dot diagrams are useful in showing the arrangement of the valence electrons in an atom. The valence electrons are the electrons in the outermost energy level of an atom and are instrumental in forming chemical bonds.

So, Lewis dot diagrams can be used to determine:

  • the charge of the ion formed
  • the oxidation number and
  • the number of bonds for the element.

But an even better use for electron dot diagrams is to join them together to form the Lewis structures of molecules or polyatomic ions.
