# What does the reaction of chromium with ozone form?

I know almost nothing beyond 10th grade chemistry. I'm trying to name a web application, and was wondering what the products are of a reaction between the element Chromium and the gas Ozone (ozonolysis of chromium?).

• Chromium Oxide, Chromia, and Chrome Green would all be options, as names for various oxides of Chromium – EnergyNumbers Aug 20 '12 at 13:39

Ozone is a strong oxidizing agent, even stronger than molecular oxygen. But it is still a donor of oxygen atoms. Thus, depending on conditions, you'll have different chromium oxides. The most stable and common chromium oxide is chromium (III) oxide $\ce{Cr2O3}$. It has numerous nicknames. Other oxides are much harder to get.
Inorganic ozonides are salts of big, inoxidizable cations, like $\ce{Cs}$ and have formulas like $\ce{KO3}$. I'm not sure which cations have ozonides that have been already produced, but to my knowledge the only reasonably easy-to-produce ozonides are $\ce{KO3}$, $\ce{RbO3}$ and $\ce{CsO3}$ by reaction of the corresponding hydroxides with ozone.
