The structure is attached below.
Step-by-step explanation:
Lewis dot structure was invented by Scientist Lewis which mainly focused on the distribution of electron on outermost shell around an atom in a molecule. It represented the atoms by their symbols and the Electron by dots. The bonds between the atoms are expressed by a straight line.
Around sulphur are 6 electrons on the outermost shell. In SF₆, the hybridization is sp³d². So there are 6 fluorine atoms around Sulphur with which fluorine forms 6 covalent bonds.
