Xenon helium compound?
If one were to say expose alpha partials to Xenon could it form Xenon-helium compounds like XeHe<sub>n</sub>--even for a fraction of a
second?

Possibly.

yeah, I suppose so. Its a stupid hypothetical question. I was thinking of how one would go about making a light saber. Because if the
He<sup>2+</sup> bound to the Xe it would take two Xe electrons with it (right?) Then that Xe<sup>2+</sup> would react with
the O<sub>2</sub> from wince it came (from XeO<sub>n</sub>
forming <u>something</u>?
Maybe interesting, but <b>I'm</b> never going to do it.

Xenon is a pretty big atom with a lot of electron wizzing arround the alpha particule should pack a punch to get anywhere near it and with more energy
to begin with the probability of a capture diminishes fast..
not impossible but a rare and short live event i`d say.
interesting to think about though

What do you think would happen if one was to spray alpha particles and XeO4 out at high speeds? I choose Xe because it is a big atom. I want the
alpha particles to interact with the Xe to make heat and light, and not to spray straight across "the battle field". Haha. I've heard of a light
saber made of partaily encapsulated plasma, but I dislike that, because the same ceramic used to contain it would be invulnerable to is powers. If my
idea were to work it could be much hotter than the boiling point of anything at atmospheric pressure.

according to Wikipedia, XeO4 is a solid stable below -36C, i guess if one could mix it with a fine powder of Polonium or Am241 i guess one could
"spray" alpha particules all over it ..
but due to its unstability , if heat is generated i would assume the whole compound would fall apart, freeing O2 and Xenon, destoying the sample in
the process
cant have heat with this stuff!

The idea would be to free the Xe and O, so that the He<sup>2+</sup> would steal two electrons from Xe making it really pissed off! Why
would I have to spray a fine powder? Couldn't I just have a source partaily enclosed by a positively charged plate?

the problem is the alpha particules are pretty heavy and carry a lot of energy (or speed) when they encounter matter they rip electrons out but still
carry some momentum .
even when they dont carry a charge anymore, and are called helium they still move too fast to be capture by chemical process . an electrical field
would accelerate the charged particules
there is always a little Helium gas coming off uranium ore due to this process
for one to be capture by an already "unwelcoming" atom like Xe is a pretty long shot ...
the result would be a charged molecule like XeHe+ and it probably wouldnt be long before an electron come along to ruin your whole day!
maybe in high vacuum where atoms and molecules are far from each other in the dark and at very low temperature they would have a better chance..
with a high flux of alpha ray the Xe is being stripped off of its electrons and Helium simply go on its way, leaving a soup of ions and electrons.

Hmm, shoot it through heavy water first? But then they would take electrons from the water, wouldn't they? Looks like its back to the drawing board!

Why not post a write-up in the corresponding thread? You took notes right? Add a little content to SciMad...
Also, it is best to edit a previous post rather then make several in a row, when possible. I know the mods are big on this, as I have been reminded
myself.

I still have to do a write up for school, Ill just post that when I get it done. I do normally edit the previous posts, but when I'm on my phone
sometimes I don't, because it can be a pain to navigate on some sites--like this one. It's weird, when I try to move the cursor on this text box it
doesn't like to go where I want it too. I'll try to edit my previous posts more now.

I remember that they managed to make kryptonite, krypton di flouride, they used a radioactive isotope of krypton gas, and florine gas, and allot of
electricity they formed a green faintly glowing crystal, that was slightly radioactive, and very very oxidizing.
History is repeating itself.

In regards to making some sort of XeHe compound i think the neutral compound is impossible since if you draw a molecular orbital there are an equal
number of electrons in the anti-bonding orbital as in the bonding orbital.
But in theory XeHe(2+) would be bonded because there would be no electrons in the anti-bonding orbital. Probably would have a very fleeting existence
but its possible at least in theory, unlike neutral XeHe.
Although if there is insufficient splitting of the molecular orbital between the bonding and antibonding orbitals then the two electrons might spread
out over both levels and once again we're back to a non-bonding situation.
i'm not sure how to resolve that last part.
