Be sure you know how to draw correct Lewis Dot Structures and are able to correctly predict the electronic arrangement and molecular geometry before going on to the lab assignment. A Lewis electron dot diagram (or electron dot diagram or a Lewis diagram or a Lewis structure) is a representation of the valence electrons of an atom that uses dots around the symbol of the element. Electrons exist outside of an atom's nucleus and are found in principal energy levels that contain only up to a specific number of electrons.
