The electron-pair geometry around the S atom in SO[tex]_{3}[/tex] is Trigonal Planar as there is Zero(0) lone pairs around the S atom.
What is electron-pair geometry?
The electron pair arrangement determines the spatial arrangement of bonds and lone pairs within a molecule. VSEPR theory is used to calculate the shape of molecules according to the arrangement of electron pairs around a central atom.
VSEPR theory states that electron pairs repel each other around the central atom and are placed as far apart as possible.
Molecular geometry is described as the 3D arrangement of atoms within a molecule, usually relative to a single central atom. Electron geometry, on the other hand, is the 3D arrangement of electron pairs around a central atom, whether bonded or unbonded.
A lone (non-bonded) pair refers to a pair of valence electrons that are not shared with another atom in a covalent bond, and a bond pair is a pair of electrons present in a bond.
Therefore, The electron-pair geometry around the S atom in SO[tex]_{3}[/tex] is Trigonal Planar.
