${SiCl}_{4}$ $"SiCl"_4$ is tetrahedral.

Explanation:

The Lewis structure of ${SiCl}_{4}$ $"SiCl"_4$ is

Lewis structure

This is an ${AX}_{4}$ $"AX"_4$ -type molecule, with four $Si-Cl$ $"Si-Cl"$ bonds.

According to VSEPR theory, these bonds must be pointing towards the corners of a regular tetrahedron.

Tetrahedron

So ${SiCl}_{4}$ $"SiCl"_4$ has a tetrahedral shape.
