In the Lewis structure for cyanate ion given below, what is the formal charge on the carbon atom? Draw Lewis structure (s) for the carbonate lon (CO₂). If there are equivalent resonance structures, draw all of them. n D co₂2: 0 . Draw one structure per sketcher box, and separate added sketcher boxes with the symbol.

Which of the Lewis structure is best at approximating the real situation becomes secondary, and it makes sense to move on from a Lewis structure model to more comprehensive models of bonding for species such as this one.
It is commonly used to determine the Lewis structure of molecules. However, the octet rule is not the end of the story. If you look at hydrogen (H) and helium (He), you will see that do not prefer an eight-electron valence, but a two-electron valence: H forms e.g. H 2, HF, H 2 O, He (which already has two electrons and doesn't form molecules).
The structure on the left follows the octet rule for both atoms, whereas the one on the right has only six electrons associated with the carbon atoms. So if you only want to write a single Lewis structure, the one on the left is better. If you have space, write the pair of resonance structures with a double arrow ($\ce {<->}$) between them.
A Lewis dot structure is a diagram showing how many valence electrons are in an atom or molecule. It shows the covalent bond in molecules, and predicts how atoms are most likely to chemically bond.
Lewis Structures Definition One of the simplest and widespread diagramming tools to show bonds between atoms is the Lewis dot structure.
On a chemistry homework, we're asked to draw the Lewis structure of $\ce{N3-}$. My answer: Nitrogen ordinarily has five electrons in its valence; $\ce{N-}$ has six. This makes a total of 16 elect...
