Verified step by step guidance1
Identify the element symbol for antimony, which is 'Sb' on the periodic table.
Recognize that 'trichloride' means the compound contains three chlorine atoms, represented as 'Cl3'.
Combine the symbol for antimony (Sb) with the subscript for three chlorine atoms to form the formula $SbCl_3$.
Check the other options to see if they match the element antimony and the correct number of chlorine atoms; for example, 'Sn' is tin, not antimony.
Confirm that the correct formula for antimony trichloride is $SbCl_3$ because it correctly represents antimony bonded to three chlorine atoms.
