A Lewis structure, also known as a Lewis dot diagram, is a visual representation of how valence electrons are distributed around atoms in a molecule, ion or radical. The bonding between atoms is depicted as a line consisting of two electrons.
To use the Lewis Structure Calculator follow these steps: Enter the formula of the molecule in the field provided for it. For example, if we want to obtain the Lewis structure of the Sulfate ion, SO 4 – 2, we must first enter the charge by typing (-2) or by entering -2 in the charge field and pressing

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.
This online quiz is intended to give you extra practice in identifying and drawing Lewis dot structures as well as predicting ion formation. This quiz aligns with the following NGSS standard (s): HS-PS1-1.
Lewis structures (also known as Lewis dot diagrams, electron dot diagrams,"Lewis Dot formula" Lewis dot structures, and electron dot structures) are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
