—Lewis Dot Structures and Molecule Geometries Worksheet Answer Key 3 4. H 2 O Total number of valence electrons: 8 CAD engineered 3D sketch model (show dipole arrows) Lewis structure: Is there a polar bond in this molecule? yes or no VSEPR shape name: bent Bond angles: 120 degrees Overall molecular polarity: polar or nonpolar 5. N 2 Writing Lewis Structures with the Octet Rule. For very simple molecules and molecular ions, we can write the Lewis structures by merely pairing up the unpaired electrons on the constituent atoms. See these examples: For more complicated molecules and molecular ions, it is helpful to follow the step-by-step procedure outlined here:

The structure shows that there are 4 electron groups around P i.e. 1 lone pair and 3 single bonds. The lone pair will push the bonds away which will give a trigonal pyramidal shape for the molecule.

Answers: a) NH3 b) ICl3 c) CO32-d) SO32-e) PCl3

The Lewis Structure of SCl2, sulfur dichloride, has a sulfur atom (which brings six valance electrons) bonded two chlorine atoms (which each bring seven valence electrons). By drawing the Lewis Structure accurately, we can determine the shape and hybridization of SCl2 as well.
