Identify the central atom and count the total number of electron domains (regions of electron density) around it. In \( \text{SCl}_4 \), sulfur (S) is the central atom.
Determine the number of bonding pairs and lone pairs on the central atom. Sulfur forms 4 bonds with chlorine atoms and has 1 lone pair, giving a total of 5 electron domains.
Recall that the electron geometry depends on the total number of electron domains (bonding + lone pairs) around the central atom, not just the bonded atoms.
Use the VSEPR (Valence Shell Electron Pair Repulsion) theory to find the electron geometry for 5 electron domains. According to VSEPR, 5 electron domains correspond to a trigonal bipyramidal electron geometry.
Note that the presence of the lone pair affects the molecular shape but does not change the electron geometry, which remains trigonal bipyramidal.
