Solution
The element Cobalt belongs to group VIII of the periodic table. It is similar to iron and nickel in its physical properties. The electronic configuration of cobalt is [Ar]3d74s2.
Co is ina +3 oxidation state in the complex [CoF6]3-.
Hence, [CoF6]3-is sp3d2hybridized and the shape is octahedral.
Therefore, according to VBT (valence bond theory), the shape of [CoF6]3-is octahedral.
