Does that decay into SHeMoNa?

Edit. Corrected my bad mixed up spelling

[-] disguy_ovahea@lemmy.world 9 points 1 week ago

Yup. Faster with a catalyst. Ma2Se, Ma2Sa are good examples.

[-] scutiger@lemmy.world 3 points 1 week ago

I believe you're thinking of SHeMoNa

[-] TachyonTele@lemm.ee 1 points 1 week ago

Lol that's perfect. Yeah i mixed it up, dammit.

[-] HEXN3T@lemmy.blahaj.zone 64 points 1 week ago

Ah yes, oxygen, my favourite metal

[-] Bishma@discuss.tchncs.de 67 points 1 week ago

Can't make fire without oxygen. That's pretty metal 🤟

Can’t make fire without oxygen

Fluorine fires have entered the chat.

[-] Viking_Hippie@lemmy.dbzer0.com 21 points 1 week ago

Fluorine fires have entered the chat.

Oh shit, someone call the fluorine fire department to save the chat!

call the fluorine fire department

Sometimes there is no such department, especially for the most vigorous fluorinating reagents like chlorine trifluoride: Sand Won't Save You This Time (Derek Lowe)

[-] Viking_Hippie@lemmy.dbzer0.com 8 points 1 week ago

it can potentially go on to “burn” things that you would normally consider already burnt to hell and gone, and a practical consequence of that is that it’ll start roaring reactions with things like bricks and asbestos tile.

Yeah, that's a big fat nope from me 😬

[-] frigidaphelion@lemmy.world 5 points 1 week ago

Lmao I think that particular emoji is sign language for love, not that that isn't appropriate here

[-] Bishma@discuss.tchncs.de 4 points 1 week ago

Even apart from sign language, it's the hand sign for "hang loose" and not "throwing horns." But was as close as I could get.

[-] moakley@lemmy.world 4 points 1 week ago

Pretty sure that's the emoji for "thwip".

[-] Morphit@feddit.uk 19 points 1 week ago* (last edited 1 week ago)

You think that's air you're breathing now?

[-] TachyonTele@lemm.ee 7 points 1 week ago

Matrix missed a great chance at an awesome unrealistic underwater flight scene.

[-] quediuspayu@lemmy.dbzer0.com 15 points 1 week ago

It sticks to a magnet, that means metal right?

[-] pHr34kY@lemmy.world 39 points 1 week ago* (last edited 1 week ago)

Do you know what happens to hydrogen when the temp drops below 14K?

Yeah. Metal.

[-] Gladaed@feddit.org 9 points 1 week ago

Metallic hydrogen may also make up parts of Jupiter's core.

[-] SasquatchBanana@lemmy.world 6 points 1 week ago

Metallic or solid? Those are two different things, and depending on the answer, i will be going down a knowledge rabbit hole

[-] Gladaed@feddit.org 4 points 1 week ago

Metals are crystal lattices with delocalized electrons.

[-] Shou@lemmy.world 2 points 1 week ago

That's fucking badass

Doesn't it also need to be under immense pressure? I don't think low temperature alone is enough.

[-] pHr34kY@lemmy.world 3 points 1 week ago

Yeah, I think that may be the case.

[-] TargaryenTKE@lemmy.world 5 points 1 week ago

That's hard af

[-] Artyom@lemm.ee 31 points 1 week ago* (last edited 1 week ago)

I'm confused, that's just a normal periodic table.

Found the astronomer.

[-] Swedneck@discuss.tchncs.de 18 points 1 week ago

what? no, a normal periodic table has oxygen and carbon too!

[-] zea_64@lemmy.blahaj.zone 34 points 1 week ago
[-] Swedneck@discuss.tchncs.de 26 points 1 week ago

i mean, i think most chemists are organic

few are free range though

[-] Balthazar@lemmy.world 23 points 1 week ago* (last edited 1 week ago)

Physicists are notorious for approximating, and astronomers are even worse. But there are some subfields where they care about being more precise, and you maybe break the periodic table into a handful of elements plus alphas. And there's that one or two people getting exquisite spectral resolution and signal-to-noise on a few stars and measuring the abundance of Technetium or whatever.

[-] peoplebeproblems@midwest.social 22 points 1 week ago

It's why I fucking love astrophysics. There's so much handwaving because so much information is observed.

But without the handwaving you can't find crazy ass things like nuclear fusion being behind the power of stars. You find these really big numbers everywhere that make the "normal stuff" negligible.

It not that the precision isn't important, it's just not always relevant at particular scales, like the scale of space.

[-] oo1@lemmings.world 18 points 1 week ago

Plutonium is not a real element.

[-] NoSpotOfGround@lemmy.world 26 points 1 week ago

It's a dwarf element.

[-] Agent641@lemmy.world 4 points 1 week ago

Plutonium can be on the periodic table but we do not grant it the rank of element.

[-] Tja@programming.dev 16 points 1 week ago

What about metallic hydrogen in the core of planets?

[-] niktemadur@lemmy.world 15 points 1 week ago* (last edited 1 week ago)

"Wait, they're ALL metals?"
"Always have been."

Funnily enough, probably not a metal according to astronomers.

[-] ornery_chemist@mander.xyz 10 points 1 week ago

Iodine is a transition metal I will die on this hill.

Care to defend your position? Iodine is certainly not in the d-block...

[-] ornery_chemist@mander.xyz 5 points 1 week ago* (last edited 1 week ago)

The intended joke is that hypervalent iodine compounds like Dess-Martin periodinane flip between different oxidation states like you often see for transition metals. As an example, the mechanism usually drawn for oxidations by DMP is similar to those drawn for PCC/Jones reagent, where the electrons removed from the substrate are "banked" at the metal center. Obviously, redox chemistry is not at all limited to transition metals, but I am often surprised at iodine's propensity to engage in it. A lot of research over the past decade or two has also developed redox catalysis with these reagents, reactivity which is commonly (though again not always) the purview of transition metals.

Should also have iron on there too

[-] RiceMunk@sopuli.xyz 4 points 1 week ago

And if you ask a cosmologist what the universe is made of, they go "Well, there's a lot of dark matter, and even more dark energy. And then there's a tiny bit of some matter or something idk lol."

[-] KairuByte@lemmy.dbzer0.com 1 points 1 week ago

Read that as cosmetologist and was thoroughly confused.

[-] propter_hog@lemmygrad.ml 3 points 1 week ago

That's because these two account for something like 99% of all normal matter in the universe
