Why is there 3 Oxygen atoms? why not 2 or 1?
and last but not least.....why do we put the negative and positive after the number when stating the oxidation number and the charge?
thanks

I did the Lewis Dot Structure for ClO3. If the Cl has 7 valence electrons, and the O has 6 valence electrons, If there is a single bond between the Cl and one O and a double bond between each of the other O, then the Cl atom would wind up with 12 electrons, if it had 7 to start, and it shares 5 with the Oxygen atoms. I don''t get it. Would that be a Polar Covalent bond? I need to memorize a bunch of polyatomic ions. I was trying to understand the reasoning for the charge when they combine, but maybe I shouldn't worry about that and just memorize the formula and the charge? thanks

The 3 Oxygen atoms are simply because it is the most convienent fit for the structure of the polyatomic ion. Two of the O atoms double bond to the Chl;orine while the third O only forms one bond, giving an overall charge of 1-. The reasoning behind the postition of the - and + is simply so it doesn't look like we're adding or subtracting.

Most of the time Chlorine (Cl) has only one bond ... like H-Cl ... which is more like an ionic bonding.
But everything has exceptions, remember covalent bonding is sharing electrons and Cl has 7 electrons to share... and ClO3 is one in a family of clorate, such as chlorate and perchlorate (ClO4).
If you draw the Lewis structure of ClO3, wherein Cl is the center atom. After working out the Lewis dot structure, you will see Cl has a single bond to one oxygen atom (which carries the negative charge) and double-bond to 2 oxygen atoms ...
If you base solely on the oxidation number, which is sometimes very hard to explain ... because each atom can have different oxidation number ... you can only assume one atom takes position of one oxidation number most of the time but not all of the time.
I hope this helps.

There are five anions of Cl:
Cl-, which is chloride with Cl in the oxidation state -1
ClO-, which is hypochlorite with Cl in the oxidation state +1
ClO2-, which is chlorite with Cl in the oxidation state +3
ClO3-, chlorate, with Cl in the oxidation state +5
ClO4, perchlorate, with Cl in the oxidation state +7

Most will continue to blame the Bush administration entirely, instead of giving most of the blame where it belongs, Congress. Both of the main parties are entirely corrupt and hypocritical and it evidences itself the most in Congressional legislation.
