The molecules have atoms held by the types of different forces like ionic, covalent, metallic, and hydrogen bonds. Te is in the same column as O so TeF2 will have the same geometry as water, OH2. In case, if molecules have a polar bond within it, their dipole moment gets canceled out with each other making the molecule a nonpolar. It means, both atoms covalently bonded have an equal distribution of charge on them. As a result, the S-F bond becomes polar and results in a dipole moment but due to symmetry, the dipoles get canceled out with each other making the SF6 a nonpolar molecule.
