Determine the total number of valence electrons. Add electrons for negative charges, subtract electrons for positive charges. 2. Place least electronegative atom (except H) as central atom in structure. 3. Connect atoms by singles bonds. Each single bond = 2 electrons. 4. “Sprinkle” remaining electrons around outside atoms first to complete octets. Don’t use more electrons than the total found in step 1. Then complete the central atom’s octet last if you have enough electrons. 5. Make double or triple bonds as needed to complete octets. 6. Place brackets and charge for ions.
