How to Write Lewis Structures
Step 1:
 
Decide which atoms are bonded.
 
Step 2:
 
Count all valence electrons
 
Step 3:
 
Place two electrons in each bond.
 
Step 4:
 
Complete the octets of the atoms attached to the central atom by adding e-'s in pairs.
 
Step 5:
 
Place any remaining electrons on the central atom in pairs.
 
Step 6:
 
If the central atom does not have an octet, form double bonds. If necessary form triple bonds.
