Final answer:
Sulfur hexafluoride (SF6) has an octahedral electron domain shape due to sp³ d² hybridization, with six bonding pairs of electrons and no lone pairs on the sulfur atom.
Step-by-step explanation:
The electron domain shape of sulfur hexafluoride, or SF6, is an octahedron. This shape is due to the fact that the sulfur atom exhibits sp³ d² hybridization. In SF6, the sulfur atom has six bonding pairs of electrons that connect to six fluorine atoms, with each fluorine atom contributing seven valence electrons. There are no lone pairs of electrons on the sulfur, and the six sp³ d² hybrid orbitals are directed towards the corners of an octahedral structure, providing the molecule its distinct shape.
