CO3^2- is called a carbonate ion. An initial we should count the total number of valence electrons. We just add the valence electron of each atoms involved.

C = 4

O = 6 x 3

e = 2 ---> we include electrons as soon as the charge of the ion is negative, in

this situation it is an unfavorable 2 for this reason we add two electrons.

------------

24 electrons

Next, we need to assign the central atom; In this instance it is C.

Now we have actually to connect the atoms and type bonds. Us can type one C=O and also two C-O bonds.

O = C - O

O

Finally, we need to distribute the staying electrons top top C atoms noted that it follow the octet rule.

O = C - O :

CO3^2- has a geometry the trigonal planar and also has a resonance. It has a bond edge of 180 degrees and the molecule is polar.
