Verified step by step guidance1
Identify the prefix 'hexa-' in the name 'sulfur hexafluoride,' which indicates the presence of 6 fluorine atoms.
Recognize that 'sulfur' refers to the element sulfur, represented by the symbol 'S' in the chemical formula.
Combine the symbol for sulfur (S) with the number of fluorine atoms indicated by the prefix 'hexa-' (6 fluorine atoms), resulting in the formula SF6.
Verify that the formula SF6 correctly represents one sulfur atom bonded to six fluorine atoms, matching the name sulfur hexafluoride.
Confirm that other options like S2F6, SF4, and S6F do not correspond to the name sulfur hexafluoride based on the number of sulfur and fluorine atoms.
