AXE Notation and Octahedral Geometry

The video tutorial explains octahedral molecular geometry, focusing on a steric number of six, where six atoms are bonded to a central atom with no lone pairs. Sulfur hexafluoride (SF6) is used as an example, illustrating the arrangement of six fluorine atoms around a central sulfur atom. The tutorial includes a 3D visualization of SF6, highlighting the 90-degree bond angles. The video concludes with a recap and an explanation of the AXE notation, specifically AX6, which corresponds to octahedral geometry.
