Although the carbonate salts of most metals are insoluble in water, the same is not true of the bicarbonate salts. a. Tetrahedral. Is CO32- Polar or Nonpolar? There is no lone pair on the central C-atom so no lone pair-bond pair and lone pair-lone pair repulsions exist in the molecular ion. Kemper, F., Molster, F.J., Jager, C. and Waters, L.B.F.M. The VSEPR chart reaffirms that the ideal electron geometry and molecular geometry or shape of a molecule with AX3generic formula are identical i.e., trigonal planar, as we already noted down for the [CO3]2- ion. Each resonance structure is a way of representing the Lewis structure of a molecule or an ion. As in the case of the isoelectronic nitrate ion, the symmetry can be achieved by a resonance among three structures: This resonance can be summarized by a model with fractional bonds and delocalized charges: Metal carbonates generally decompose on heating, liberating carbon dioxide from the long term carbon cycle to the short term carbon cycle and leaving behind an oxide of the metal.

Electronegativity is defined as the ability of an atom to attract a shared pair of electrons from a chemical bond. Your email address will not be published. Now, when chemical bonding occurs, these AOs come together and combine to form hybridized orbitals that take part in the formation of bonds inside a molecule. Polar molecules (those with an appreciable dipole moment) interact with electric fields, whereas nonpolar molecules do not. "@type": "Answer", Here, we can follow the AXn notation to find out the exact molecular geometry of CO32- ion.
