Lewis Dot Structures Worksheet
Lewis Dot Structures Worksheet Name:
For the elements listed below, draw in the correct Lewis Dots for the atom.
For the compounds listed below, draw the correct Lewis Dot Structure.
Drawing Lewis Dot Structures
1. Add up the total number of valence electrons in the molecule by totaling the valence
electrons on each atom in the molecule or polyatomic ion.
2. Draw the skeleton structure of the molecule or polyatomic ion in which the covalent
bonds between the atoms are drawn as single lines. Each bond equals two valence
electrons. If the molecule has more than two atoms, the atom with the lowest
electronegativity is generally listed first and is the central atom and is written in the
3. Distribute valence electrons around the outer atoms as nonbonding electrons to until each
atom has a complete outer shell (8 electrons except for H which has only 2 valence
4. Add the remaining valence electrons to the central atom.
5. Check the central atom.
o If the central atom has eight electrons surrounding it, the Lewis Structure is
o If the central atom has less than eight electrons, remove a nonbonding electron
pair from one of the outer atoms and for a double bond between that atom and the
central atom. If needed, continue to remove nonbonding electron pairs from the
outer atoms until the central atom has a complete octet.
