Transcript: Lets do the CO3 2- Lewis structure: the carbonate ion. Carbon has 4 valence electrons; Oxygen has six, we have 3 Oxygens, and this negative 2 means we have an extra two valence electrons. Add that all up: 4 plus 18 plus 2: 24 valence electrons. Carbon is the least electronegative, put that at the center.

Also, is co3 2 a resonance structure? The Carbonate (CO2−3) Ion Like ozone, the electronic structure of the carbonate ion cannot be described by a single Lewis electron structure. Unlike O 3, though, the actual structure of CO 3 2− is an average of three resonance structures.

Also asked, how many Lewis structures does co32?

There are three different possible resonance structures from carbonate. Each carbon oxygen bond can be thought of as 1.333 bonds. the average of a double bond and 2 single bonds. 4 bonds/3 structures.

Is co3 2 polar or nonpolar?

oh! and by the way, CO3 2- is an ION, not a molecule. A negatively charged ion is POLAR, because it is not electrically neutral, on account of its negative charge (TWO of them). And, carbonate doesnt have two single bonds and a do
