Final answer:
The chemical formula for Silicon Tetrabromide is SiBr4, which consists of one silicon atom bonded to four bromine atoms.
Step-by-step explanation:
The chemical formula for Silicon Tetrabromide is SiBr4. This is because the name indicates the compound consists of a silicon atom (Si) and four bromine atoms (Br4). The prefixes in the compound's name represent the number of atoms of each element present in the molecule; 'tetra-' means four, so it's understood that there are four bromine atoms bonded to one silicon atom, reflecting the stoichiometry of the compound.
