CO2 does not have unshared pairs of electrons.

A Lewis structure is a model that uses electron-dot structures to show how electrons are arranged in molecules. Pairs of dots or lines represent bonding pairs this is a CO32− model
The answer to the quest is not zero
H2CO. The oxygen will have two pairs of non-bonding electrons
CO2 does not have unshared pairs of electrons.

lone pairs
B is in the center, with the three F's around it. Two F's have three lone pairs of electrons and one F has two lone pairs and a double bond with B.
The difference between the Lewis dot structure and the structural formula is that the formula only shows the bonds that have formed whereas the dot structure shows all the valence electrons, including lone pairs, in that molecule.

When there are not enough valence electrons to complete octets by adding unshared pairs. Source: My Chemistry Textbook :D
The Lewis dot for lithium nitride (Li3N) would show 8 electrons (4 pairs) on the N with a -3 charge and no electrons on the 3 Li with each having a +1 charge.
