Carbon and Its Compound


What would be the electron dot structure of carbon dioxide which has the formula CO2?


The atomic number of carbon is 6 and its electronic configuration is (2, 4). While the electronic configuration of oxygen is (2, 6). This means that carbon needs four electrons while oxygen needs two electrons to complete their octet. So, the carbon shares two electrons each with the oxygen atom. This means that CO2 contains two carbon-oxygen bonds. The electron dot structure of carbon dioxide is shown below:
