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
