Determine the electron geometry (eg), molecular geometry (mg), and polarity of SF6.
eg = tetrahedral, mg = octahedral, nonpolar
eg = octahedral, mg = octahedral, nonpolar
eg = trigonal bipyramidal, mg = trigonal bipyramidal, polar
eg = octahedral, mg = trigonal bipyramidal, nonpolar
eg = trigonal bipyramidal, mg = seesaw, polar
