Verified step by step guidance1
Identify the central atom in the molecule SO_3, which is sulfur (S).
Determine the number of valence electrons for sulfur and oxygen atoms. Sulfur has 6 valence electrons, and each oxygen has 6 valence electrons.
Draw the Lewis structure of SO_3 by connecting sulfur to three oxygen atoms with double bonds to satisfy the octet rule for all atoms.
Count the regions of electron density (bonding and lone pairs) around the central sulfur atom. In SO_3, there are three bonding regions and no lone pairs on sulfur.
Use the VSEPR theory to determine the electron geometry based on the number of electron density regions. Three bonding regions and no lone pairs correspond to a trigonal planar electron geometry.
