Answer
Electron geometry: tetrahedral
Molecular geometry: tetrahedral
Idealized bond angle: $109.5^{\circ}$
Deviation from idealized bond angle : no
Work Step by Step
$CF_4$ has 4 covalent bondsand no lone pairs on the C atom. Its electron geometry is tetrahedral. Its molecular geometry is also tetrahedral since C atom is bonded to 4 F atoms. Its idealized bond angle is that of the tetrahedral geometry, $109.5^{\circ}$. There is no deviation from the idealized bond angle.
