Draw the lewis structure of co. include lone pairs and formal charges.

See attached picture.

Explanation:

Hello,

In this case, Lewis structures are representations showing the elements valence electrons and how they are connected with other elements throughout lines (bonds). Thus, for carbon, which has four valence electrons, and oxygen, which has six valence electrons (by looking their groups), the Lewis structure is shown on the attached picture wherein it is seen the presence of a double bond in order to attain the octet (8 electrons in total for both carbon and oxygen)

Best regards.
