The silicon tetrafluoride has tetrahedral molecular geometry and it shows sp3 hybridization at the central silicon atom.
Contents
Silicon has 4 valence electrons. One valence electron from $3s$ is excited to $3p$. The atom undergoes $s{p^3}$ hybridisation. All four hybrid orbitals form bond pairs and the structure is tetrahedral.
As we can clearly see, Silicon hydride or Silane has a tetrahedral molecular geometry. The approximate bond angle for a general tetrahedral 3D molecule is 109 degrees.

SiH4. What is the molecular geometry of a molecule with 4 outer atoms and 1 lone pair on the central atom? tetrahedral.
SiH4 is non-polar. The Si–H bonds are polar, because of differing electronegativities of Si and H. However, as there are 4 electron repulsions around the central Si atom, the polar bonds are arranged symmetrically around the central atom / tetrahedral shape.
In the molecule SiH4 the central atom Si has 4 valence electrons where the Si atom is forming 4 sigma bonds with H atoms and therefore the stearic number of Si is 4 which imply that the hybridization of the molecule is sp3 where the geometry and the shape is tetrahedral.
