The incomplete Lewis structure below shows all the atoms and sigma bonds for a particular molecule, but nothing else. The molecule has a net charge of +1. Fill in any missing electrons to create the best Lewis structure for the molecule. Make sure to include any non-zero formal charges. НН H H H. H. H. H H. H.

The carbonate anion, CO32- , is a resonance hybrid. Draw all of the important resonance structures for this molecule. If an atom has a nonzero formal charge, be sure the formal charge is shown clearly in the structure. Use the resonance structures to calculate the average formal charge on each O atom (which are all equivalent in the "true" structure). [Note: all of the important contributing resonance structures have octets around each atom that desires an octet.]

An incomplete Lewis structure is shown below. The structure only shows the atoms and how they are connected. The molecule has a net charge of zero. H Н—N—С- -о—с—Н H H Complete the Lewis structure giving all atoms full octets. If there is more than one way to do this, draw resonance structures showing all possibilities. If not, just draw one Lewis structure. Be sure to write in any non-zero formal charges. Click and drag to start drawing a structure.

The azide ion, N3, is a symmetrical ion, all of whose contributing structures have formal charges. Draw three important contributing Lewis structures for this ion. Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all nonbonding electrons. Show the formal charges of all atoms in the correct structure. Q Q Q ?
