The Carbonate (CO2−3) Ion 2. Carbon has 4 valence electrons, each oxygen has 6 valence electrons, and there are 2 more for the −2 charge. This gives 4 + (3 × 6) + 2 = 24 valence electrons.

As an example, let's use carbon tetrachloride, CCl4. The single carbon atom contains four valence electrons, and each of the four chlorine atoms contains seven valence electrons. Therefore, the number of valence electrons for this molecule is 4 + (4 × 7) = 32.

We need to know how many electrons are available to make the bonds for Phosphate Ion. Phosphorus is in group VA so it has 5 valence electrons and Oxygen is in group VIA so each oxygen has 6 valence electrons. Total valence electrons = 5 + 4(6) = 29.

The cyanide ion formula is CN–. That gives us ten valence electrons in total to work with.

Forming Covalent Bonds A fluorine atom has seven valence electrons. If it shares one electron with a carbon atom (which has four valence electrons), the fluorine will have a full octet (its seven electrons plus the one it is sharing with carbon).

So we've used all 24 valence electrons and each of the atoms in H2CO3 has a full outer shell. So that's the Lewis structure for H2CO3.

Count the valence as before then addan electron for each unit of negative charge or subtract one foreach unit of positive charge. For example, the sulfite ion has theformula SO32-. The number of valence electronsis 6 + 3*6 + 2 = 26.
