Electron dot structures or Lewis dot formula – It defines the nature of bond and position of atoms of the molecule which are connected in the molecule.
Electron dot structures of carbon dioxide
- The carbon is the central atom of this molecule.
- Oxygen atom contains 6 valence electrons which form 2 lone pairs. Since it is bonded to only one carbon atom, it must form a double bond.
- Carbon atom contains four valence electrons, resulting in zero lone pairs. Therefore, it is doubly bonded to each oxygen atom.
