Answer:

C. tetrahedron

Explanation:

Silicon tetrabromide (SiBr₄)

Valence electrons of silicon = 4

Valence electrons of bromine = 7  

The total number of the valence electrons  = 4 + 4(7) = 32

The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So,  the lewis structure is shown in the image below.

Around the central metal atom:-

Number of bond pairs = 4

Number of lone pairs = 0

The formula is AB_4.

<u>According to VSEPR theory, silicon tetrabromide has tetrahedron shape to minimize the repulsions. </u>

It would form a negative ion... it lacks 1 e in its valence shell., it is easier for F to accept an e than to shed all existing 7.
e= electron
