The correct Answer is:

To determine which statements about the carbonate ion \( \text{CO}_3^{2-} \) are correct, we can analyze the structure and properties of the ion step by step. ### Step 1: Understanding the Structure of \( \text{CO}_3^{2-} \) The carbonate ion consists of one carbon atom centrally located and bonded to three oxygen atoms. The overall charge of the ion is -2. The structure can be represented as follows: - Carbon is bonded to three oxygen atoms. - There are resonance structures due to the delocalization of electrons.
