Verified step by step guidance1
Identify the chemical formula given: SiCl_4. This formula represents a molecule composed of silicon (Si) and chlorine (Cl) atoms.
Understand that in chemical formulas, the subscript number following an element symbol indicates the number of atoms of that element in one molecule or formula unit.
In SiCl_4, the subscript '4' is written immediately after Cl, which means it refers to the number of chlorine atoms bonded to one silicon atom.
Recognize that the absence of a subscript after Si implies there is only one silicon atom in the molecule.
Therefore, the number '4' in SiCl_4 specifically represents the number of chlorine atoms bonded to a single silicon atom.
