I have been trying to draw this lewis structure for a few hours, and c an't get it for the life of me. I know Cl has 7 valence electrons, and O has 6. And ClO3 has a negative charge, but I can't draw it. Please help!

I need to know how many single bonds, double bonds, and lone pairs there are.

It is just Cl single bonded to each of the O's. Ther are 26 available electrons (7+(6*3)+1(because it is negative)) and to fill their valence shells 32 are needed which means 6 are shared which means there are 3 bonds and since all of the atoms must be bonded there must be 3 single bonds. There are 10 lone pairs I think(you can check)

I assume you understand part a So part b. Formal charge is basically the difference between the number of electrons on an atom in the bond compared to the number of valence electrons it has(a single bond counts as 1 election while a double bond counts as 2). So we want to try to give each oxygen 6 elections to try to minimize the formal charge. The Cl is the central ion, so we draw that with sp3d2 hybridization. Then you draw 2 oxygens with double bonds to the Cl(these will have a formal charge of zero and have 4 more electrons on them). The last oxygen must be single bonded with 6 additional electrons around it. so the chlorine should have 2 oxygens double bonded and 1 oxygen single bonded and one lone pair. This structure has resonance because the double bonds may be on any of the 2 oxygens, so it constantly changes. Hope that's not too confusing...good luck!

The first step in drawing any lewis structure should be to add up the total # of valence electrons. Therefore, in the ClO3- ion there are 26 electrons. Since there are three oxygens and one chlorine, u should immediately realize that chlorine would be the central atom. Next draw three bonds (6 electrons) around chlorine to bond with the oxygen. Next, complete the octets of oxygen and chlorine and you will end up with 26 electrons which is the total # of valence electrons that you calculated b4. Since there are 3 single bonds and one lone pair on the central atom, the shape of the structure would be trigonal pyramidal.

The chlorine is the central atom. The Oxygens are double bonded to the Cl. And there is a lone pair on the Cl. so if you count all the bonds and electrons on Cl there are eight, and like you siad Cl has seven valence electrons and it would have a minus charge. Like the picture in the link, but with out the OH group.
Hope that helps
