Verified step by step guidance

Understand the analogy between the silicate ion and the carbonate ion. The carbonate ion is CO3^{2-}, which consists of one carbon atom bonded to three oxygen atoms, with a net charge of -2.

Apply the same structural concept to the silicate ion. The silicate ion will have one silicon atom bonded to oxygen atoms, similar to the carbonate ion's structure.

Consider the possible charges for the silicate ion. The carbonate ion has a charge of -2, so the silicate ion should also have a similar charge to maintain the analogy.

Evaluate the given options: SiO3^{4-}, SiO3^{3-}, SiO3^{2-}, SiO2^{2-}, and SiO2^{3-}. The correct structure should have one silicon atom bonded to three oxygen atoms with a charge of -2.

Select the correct structure based on the analogy and charge: SiO3^{2-} is the silicate ion that matches the structural and charge characteristics of the carbonate ion.
