SF6 is unreactive towards water because it is a non-polar molecule with strong covalent bonds, making it difficult for water molecules to break these bonds. TeF6, on the other hand, is reactive with water because it contains a metal (tellurium) and highly electronegative fluorine atoms, resulting in a more polar molecule that can easily react with water to form products.

Octahedral
The bond angle of TeF6 is 90 degrees. This is because TeF6 adopts an octahedral geometry with the six fluorine atoms surrounding the central tellurium atom. Each fluorine atom occupies one of the six vertices of an octahedron, resulting in bond angles of 90 degrees between adjacent fluorine atoms.
No its not polar
The Lewis structure for TeF6 (tellurium hexafluoride) consists of a central tellurium atom bonded to six fluorine atoms. Tellurium has 6 valence electrons, and each fluorine contributes one valence electron, totaling 12 electrons. The structure will have 12 total valence electrons arranged so that each fluorine atom is bonded to the tellurium atom with single bonds.
The Lewis dot structure for TeO3 has a central tellurium (Te) atom bonded to three oxygen (O) atoms. The tellurium atom will have six dots around it, representing its valence electrons, and each oxygen atom will have two dots, indicating a single bond with the tellurium atom.
