A Lewis or Electron Dot Structure is a convenient representation of the valence electrons in an atom. An electron dot structure for an atom is simply the symbol for the element, surrounded by a number of dots equal to the number of valence electrons.
LEWIS STRUCTURES PRACTICE WORKSHEET. Draw the Lewis Structures for each of the following molecules. If you are not sure if your structure is correct, do a formal charge check. You should consult the Lewis structure rules and a periodic table while doing this exercise.
Lewis Dot Structures and Molecule Geometries Worksheet. How to Draw a Lewis Dot Structure. Find the total sum of valence electrons that each atom contributes to the molecule or polyatomic ion. You can quickly refer to the periodic table for the group A number for this information.
