Experimental analysis of solid \(\text{CaCO}_3\) indicates that all three carbon-oxygen bonds in the carbonate ion, \(\text{CO}_3^{2-}\), are identical in length at \(128 \text{ pm}\). For comparison, typical \(\text{C}-\text{O}\) single bonds average \(143 \text{ pm}\) and typical \(\text{C}=\text{O}\) double bonds average \(122 \text{ pm}\). Three Lewis diagrams for the carbonate ion are shown below. Which of the following claims is best supported by these representations and the experimental bond length data?
