Fill in the following tables using these steps to convert a molecular formula to a molecular shape. Step 1 – Write the Lewis structure from the molecular formula. Step 2 - Assign an electron-group arrangement by counting all electron groups (bonding plus nonbonding) around the central atom. Step 3 - Determine the number of bonded atoms and lone pairs around the central atom Step 4- Predict the Molecular shape using the number of bonded atoms and lone pairs.
