4. Fill in the table givingthe number of valence electrons, Lewis Structure, sketch, electron pair geometry (EP), molecular geometry (MG), Bond Polarity (BP) and Molecularpolarity. TablesofMolecular/Electron pair geometry and Electronegativity values are on page 147.
5. Draw Lewis Structure and make model of your assigned molecule.
6. Your Lab Instructor will initial theTitlePage of Your Lab to indicate that you have attended the lab, completedthe required lab activities, cleaned your lab bench andallequipmentused,andreturnedalllabequipmenttoitsdesignatedspace. A Lab Report that is not initialed in the Checkout box may not be graded. It is at the discretion of your Lab Instructor.
