Problem: The Lewis diagram for SO3: The electron-pair geometry around the S atom in SO3 is ____There are lone pair(s) around the central atom, so the geometry of SO3 is ____

FREE Expert Solution

For this, we need to do the following steps:

Step 1: Determine the central atom in this molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.

Step 4: Determine the molecular geometry and shape of the molecule.


Step 1: Sulfur (EN =2.5) is less electronegative than oxygen (EN = 3.5) so S is the central atom.


Step 2: We need to determine the total number of valence electrons present in the molecule:


            Group             Valence Electrons

S         6A                  1 × 6 e =  6 e

O        6A                   3 × 6 e18 e

           Total = 24 valence e


Step 3: Draw the Lewis Structure
