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 e– = 18 e–
Total = 24 valence e–
Step 3: Draw the Lewis Structure
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 ____
