Each oxygen atom inside the ion has four non-bonding electrons. In an octahedral arrangement with two lone pairs, repulsion is minimized when the lone pairs are on opposite sides of the central atom. Molecular structure describes the location of the atoms, not the electrons. However, carbonate ion is an exception to the rule. So, the AXN generic formula for the [CO3]2- ion is AX3. A carbonate salt forms when a positively charged ion, M+, M2+, or M3+, associates with the negatively charged oxygen atoms of the ion by forming electrostatic attractions with them, forming an ionic compound: Most carbonate salts are insoluble in water at standard temperature and pressure, with solubility constants of less than 1108. Therefore, the very first step while drawing the Lewis structure of [CO3]2-is to count the total valence electrons present in the concerned elemental atoms.
