Lewis structure of CO

Step method to draw lewis structure of Carbon Monoxide

Step 1: Find valence e- in all atoms. Add them together.

Step2: Find octet e- for each atom and add them together.

Step3: Gives you bonding e-. Subtract step 1 total from step 2

Step 4: Find number of bonds by diving the number in step 3 by 2(because each bond is made of 2 e-)
6e-/2= 3 bond pairs

Step 5: Find the number of nonbonding (lone pairs) e-. Subtract step 3 number from step 1.
10-6= 4e-=2 lone pairs

Use information from step 4 and 5 to draw the lewis structure.
Put both atoms side by side since there are only two atoms.

Lewis dot structure of CO

Alternatively a dot method can be used to draw the lewis structure of CO.
Calculate the total valence electrons in CO molecule.


Put both elements side by side..
Put a pair of electrons connecting the side atom with central atom.Pur remaining electrons on the side atoms.Move electrons from side atoms until both elements gets 8 electrons
