Ask Lemmy
A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, and toxicity are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either [email protected] or [email protected].
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.

Oxygen is found in 3 forms: nascent (O), molecular (O2, the most common) and ozone (O3). Nascent oxygen, due to its electronic configuration (i.e how many electrons it has and how they're spread out across its electronic shells) is unstable, and tends to quickly form bonds with another O, forming O2. This is also the case e.g. for hydrogen, which is usually found as H2.
You can find O in this form in some environments, in the upper atmosphere there is enough UV radiation to break up O2 into O.
So simply because it's so reactive the most common form is oxygen paired with itself?
Not just with itself, also with other elements. Say, you won't find pure iron in the wild either, because normally it reacts with oxygen so well.
But yea oxygen needs to pair with something because its outer electron shell is incomplete. So pairing with another oxygen atom is likely, but also with whatever else is available - nitrogen, iron, whatever.
Most elements are found in molecules really, with the exception of noble gasses like Helium. And some are less reactive than others.
This is an ELI5 explanation. Well done💯💯
Yes, that's right.
You can pair H with O, and have a good time.
I don't know if anyone is interested but there would be more versions too. Solid oxygen (red oxygen) at high pressure used to be thought of as O4, tetraoxygen aka oxozone. But if you look at it with x-ray crystallography it's O8, octaoxygen. Cool huh
I had no idea, but yeah that's very cool!
Is solid oxygen an amorphous mass of O4 and O8? Why doesn’t it form crystals?
Can you breathe just O by itself without it being in O~2~ molecule?
Edit: I did some searching and apparantly you couldn't breathe just an Oxygen atom by itself, it needs to be an O~2~. (Correct me if I'm wrong)
This question doesn't even make sense. If atomic oxygen somehow magically appeared in your respiratory tract, it would immediately react with itself and probably burn you to death.
Yes. Nascent oxygen (O) is very reactive, somewhat like peroxide and ozone, so it could be used to burn off organic matter.
Now, if you don't want it to react (too fast) with itself and produce molecular oxygen you may dilute it at low concentration into some inert gas (nitrogen or helium for example).
Taking 2 or 3 breath of this gas mixture once in a while would eventually get @WtfEvenIsExistence1 with Acute inhalation injury
I suspect it would rapidly react and give off energy as heat. This would likely be incompatible with life.
