What should the formal charge for the central atom of ClO2+ be. Should it have a charge of one because it is positively charged overall. I don't quite understand which formal charge should go on what molecule.
The formal charge of the Cl atom in ClO2+ can be +1 because the net charge of the all of the atoms should equal the net charge of the polyatomic ion which is +1 in this case. If both of the Cl-O bonds are double bonds then the two oxygen atoms have a formal charge of zero, and the formal charge of the Cl atom is +1. 0+0+1= 1 which is the net charge of all of the atoms and is also the charge of the ClO2+ molecule. Also, the more electronegative elements(Oxygen in this case) should have the more negative charge ( 0 vs 1 )

Oh, I figured it out. The formal charge of the central atom, Cl, in ClO2+ is actually has a formal charge of +1 because there is going to be a positive charge on the atom because of the charge. Oxygen is more electronegative than Cl, so it wants to have a full octet. So the formal charge of the oxygen is 0 and the formal charge of Cl is +1.
I appriciate the response.
