Identify the chemical formula given: SF_6, which consists of one sulfur (S) atom and six fluorine (F) atoms.
Recall the rules for naming binary molecular compounds (compounds made of two nonmetals): use prefixes to indicate the number of atoms of each element, and the second element's name ends with '-ide'.
Determine the prefix for the number of fluorine atoms: 'hexa-' means six, so the fluorine part becomes 'hexafluoride'.
Name the first element (sulfur) without a prefix if there is only one atom, so it remains 'sulfur'.
Combine the parts to form the correct name: 'sulfur hexafluoride'.
