Build or draw the Lewis structure for each of the molecules listed below. H2O, NH, CHI, CO 2. Build or draw a model of each of the Lewis structures using any of the materials listed above (See lesson for an example). Here are the steps: a. For each molecule, represent each element with a spherical (ball shaped) object. B. Each single bond should be represented with a straight object, two straight objects should be used between two atoms to represent a double bond, ND three straight objects should be used between two atoms represent a triple bond. . Remember that the lone pairs on the central atom take up space and play a role in determining the shape of the molecule. Represent each lone pair (nobodies pairs of valence electrons) on the central atom with a nobodies object. The bonds and lone pairs on the central atom should be spread apart as much as possible. See example in lesson as a reference. Conclusion For each of your molecular models, include a Lewis structure drawing or picture f your model (1 point for each molecular drawing).

On your drawing or picture, include the following information: 1. What is the central atom? (1 point for each molecule) 2. How many atoms are bonded to the central atom? (1 point for each molecule) 3. How many lone pairs of electrons are on the central atom? (1 point for each molecule) 4. How many single bonds are there in this molecule? (1 point for each molecule) 5. How many multiple bonds (double and/or triple) are there in this molecule?
