From Diatomic Oxygen to Peroxide

"Small, but detectable, amounts of hydrogen peroxide can be formed by several methods. Small amounts are formed by electrolysis of dilute acid around the cathode where hydrogen evolves if oxygen is bubbled around it."

Many Thanks for interesting replay, can molecular peoxide be produces from oxygen.

Is it possible

Is something expected from this forum that cannot be found in Wikipedia?

..."Peroxides are a group of compounds with the structure R−O−O−R.^[1] The O−O group in a peroxide is called the peroxide group or peroxo group. In contrast to oxide ions, the oxygen atoms in the peroxide ion have an oxidation state of −1.

The most common peroxide is hydrogen peroxide (H₂O₂), colloquially known simply as "peroxide"."...

many thanks,

you know I am not specialized in chemistry, so may the question is not clear enough producing H2O2 not the target, I am asking about molecular oxygen peroxide (O2)-2.

Is there a method to generate it.

Oxygen is O₂ or O₂(2−), a molecule of O ...

Oxygen peroxide? Perhaps you mean ozone. Ozone (O₃) can be generated from diatomic oxygen (O₂) in an electric arc. Also, short-wavelength ultraviolet radiation (UVC) will generate ozone from diatomic oxygen. The ozone layer in the upper atmosphere is generated in this way by ultraviolet radiation from the sun.

Why don't you just tell us what you're trying to do, so we can cut to the chase...?

Re-entering the atmosphere from orbit is one way.

Noble gases are the only elements that exist in nature as uncombined atoms."...

How about mercury vapor...?

That appears to be a dated reference...

Granted its vapor pressure is pretty low at ambient temperatures, but I'm still pretty sure Hg is monatomic as a gas. Mercury atoms have very little attraction for each other, which is why mercury is liquid at room temperature.

It may be monatomic under certain conditions, but it's not stable in that state...

Maybe I missed it, but I didn't see anything in the Britannica article that contradicts what Rixter said. Can you point it out?

Can you cite a recent reference confirming it?

https://www.jstor.org/stable/96492?seq=1

Yeah I saw that, from 1935....somewhat theoretical....any corroborating evidence?

Source: The Properties of Matter

The adiabatic constant, γ=Cp/Cv, is the ratio of the specific heat (ΔH/ΔT) for constant pressure Cp and constant volume Cv. γ= 1.666 (5/3) for monatomic gases and 1.4 (7/5) for a diatomic gas. It has to do with degrees of freedom of vibration of the atoms or molecules. Diatomic molecules have more degrees of freedom, f, than atoms. γ=(f+2)/f, where f = 3 for monatomic gases and f = 5 for diatomic gases.

The velocity of sound also depends on the adiabatic constant, γ.

http://hyperphysics.phy-astr.gsu.edu/hbase/Sound/souspe3.html

So, measuring the velocity of sound in mercury vapor determines the adiabatic constant, γ. The velocity of sound in mercury vapor was measured as far back as 1876 indicating that γ = 1.66 (monatomic gas).

Please don't change the subject.

See #17...I'm not contesting that mercury vapor can be considered monatomic under certain conditions .... but this has little to do with oxides, or peroxides...

So what? I wasn't talking about (per)oxides. I was talking about mercury vapor, which you allege to be in an unstable condition. So long as voltage is maintained on a mercury vapor lamp, its condition is likely stable. (Until power is turned off.)

Good ol’ Wikipedia...

Maybe he wants to build one of these, and run it on water...

and this...

So it can be done with some extra oxygen...

...Hydrogen peroxide is H2O2. Thus water cannot be rearranged. You will in principle either need to add oxygen or produce H2O2 and hydrogen. The simplest sequence of reactions is to electrolyze water into H2 and O2, and then combine these via the Anthraquinone process - Wikipedia ."...

Isn't it annoying when an Original Poster abandons a thread without telling the forum what is wanted to be achieved?

Nobody seems to have said it explicitly, but, I think that the cocensus here is that no such thing (peroxide with no other element) exists.

^{I guess you'd have to call it super ozone if it did?}
