Molecular Geometry of SF6

The video tutorial explains the molecular geometry of sulfur hexafluoride (SF6). It begins with the Lewis structure, showing sulfur as the central atom bonded to six fluorine atoms with no lone pairs. The model demonstrates the octahedral shape, with bond angles of 90 degrees. The electron geometry is also octahedral due to the absence of lone pairs. The steric number is 6, confirming the octahedral geometry. The AXN notation is used to describe the structure as AX6, reinforcing the octahedral shape. The video concludes with a reference to a table for further understanding.
