Verified step by step guidance1
Identify the central atom in the molecule, which is sulfur (S) in SCl\_4.
Determine the number of valence electrons for sulfur and chlorine atoms. Sulfur has 6 valence electrons, and each chlorine has 7 valence electrons.
Calculate the total number of valence electrons in the molecule by adding sulfur's valence electrons to those of the four chlorine atoms.
Use these electrons to draw the Lewis structure, placing sulfur in the center and bonding it to four chlorine atoms. Then, count the number of electron domains (bonding and lone pairs) around sulfur.
Apply VSEPR theory: the electron geometry depends on the total number of electron domains around the central atom. For SCl\_4, with four bonding pairs and one lone pair, the electron geometry is trigonal bipyramidal.
