1. For each molecule and ion below, indicate the total number of valence electrons. Based on that number of electrons, draw a valid Lewis structure.2. Use VSEPR theory to determine the electron arrangement and the geometry of the molecule around the central atom(s). A table of geometries is attached.3. Build the molecule using the molecular models provided in the lab. Sketch your model well enough to show the geometry. Include bond angles.4. Using your understanding of electronegativity and its trends in the Periodic Table, determine if polar bonds exist in the molecule.5. Using bond polarity and molecular shape, determine if the molecule has an overall dipole. If all the bonds are nonpolar, the molecule is nonpolar. If polar bonds are present, then consider the shape to determine if the molecule has an overall dipole.

You will not find “hydroxide” in the stockroom, but you will find sodium hydroxide (NaOH) andpotassium hydroxide (KOH). Lithium hydroxide (LiOH) is expensive and used in spacecraft airfilters since hydroxide reacts with carbon dioxide, and lithium is lighter than sodium or potassium.Cesium and francium hydroxides are very expensive and little used. Is this information consistentwith your answer to the previous question?
