118 differing electronegativity. Modify the second structure given to draw the new resonance structure. Include lone pairs and charges in your structure. Use the + and - tools to add charges to an atom, and use the single bond tool to add/remove double bonds. 'H Edit Drawing :O:

Steps for Lewis Structures: 1. 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. For the central atom in each formula, draw the Lewis Structure with all valence electrons shown. 1. PH3 2. H2O 3. CO2 4. CHCl3 5. O2 6. N2 7. CF4 8. C3H8 9. CH3COOH 10. N2O 11. OCN-
