Thread: Oxidation state of Oxygen

I'm pretty sure that somewhere I learned about a compound in which Oxygen has a charge of +1. Can anyone tell me what this compound is?
<maybe i'm just crazy, guess i'll find out soon enough> thanks.

I guess if you reacted it with something in group 17 it would have a +1 charge... maybe..

Oxygen normally has an oxidation state of -2, but the +1 may be present in a number of polyatomic ions such as NO2-, SO42-, etc or with coordination compounds with a central atom as a metal. In these cases, the whole molecule has the charge and the atoms inside of it don't "add up" in general chemistry terms. Hope this helps.

first of all when it comes to charge it only accounts for ions, and as individual the oxygen atom rarly gets +1.
oxygen does how ever allways gets the oxidation number -2, exept peroxides where its -1, wich it doesnt like. thats why perroxides reacts farly quickly.

also Mick_Mills, SO42- can be thought to mean a sulphur with 42 oxygens bound to it with a charge of - at the end, i think its better to write like SO4 (2-) to show its the charge. in that one oxygen have the OS -II, and sulphur +VI
NO2 (2-) does oxygen still have OS -II and nitrogen has +IV

but of course there is possible to get the oxygen ion O+ but its rare
