A step-by-step explanation of how to draw the H2CO3 Lewis Dot Structure (Carbonic Acid).
For the H2CO3 structure use the periodic table to find the total number of valence electrons for the H2CO3 molecule. Once we know how many valence electrons there are in H2CO3 we can distribute them around the central atom with the goal of filling the outer shells of each atom.
In the Lewis structure of H2CO3 structure there are a total of 24 valence electrons. H2CO3 is also called Carbonic Acid.
When we have an H (or H2) in front of a polyatomic molecule (like CO3, SO4, NO2, etc.) we know that it's an acid. This means that the Hydrogen atoms will be attached to the outside of the oxygen molecules. Not knowing this information makes it very difficult to draw the Lewis structure for H2CO3.
---- Steps to Write Lewis Structure for compounds like H2CO3 ----
1. Find the total valence electrons for the H2CO3 molecule.
2. Put the least electronegative atom in the center. Note: Hydrogen (H) always goes outside.
3. Put two electrons between atoms to form a chemical bond.
4. Complete octets on outside atoms.
5. If central atom does not have an octet, move electrons from outer atoms to form double or triple bonds.

Lewis Structures, also called Electron Dot Structures, are important to learn because they help us understand how atoms and electrons are arranged in a molecule, such as Carbonic Acid. This can help us determine the molecular geometry, how the molecule might react with other molecules, and some of the physical properties of the molecule (like boiling point and surface tension).
