Verified step by step guidance1
Identify the prefix 'hexa-' in the name 'sulfur hexafluoride,' which indicates the presence of 6 fluorine atoms.
Recall that 'sulfur' corresponds to the element symbol 'S' and 'fluoride' corresponds to the element symbol 'F'.
Combine the symbols with the correct number of atoms: one sulfur atom (S) and six fluorine atoms (F6).
Write the chemical formula by placing the number of fluorine atoms as a subscript after 'F', resulting in 'SF6'.
Verify that the formula matches the name: sulfur hexafluoride corresponds to SF6, confirming it is the correct formula.
