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 😬

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.

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.

That’s because these two account for something like 99% of all normal matter in the universe
What about metallic hydrogen in the core of planets?

Funnily enough, probably not a metal according to astronomers.

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.
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.”

*The Periodic Table according to Michael Jackson
He~2~
Does that decay into SHeMoNa?
Edit. Corrected my bad mixed up spelling
Yup. Faster with a catalyst. Ma2Se, Ma2Sa are good examples.
I believe you’re thinking of SHeMoNa
Lol that’s perfect. Yeah i mixed it up, dammit.
Ah yes, oxygen, my favourite metal
You think that’s air you’re breathing now?
Matrix missed a great chance at an awesome unrealistic underwater flight scene.
Can’t make fire without oxygen. That’s pretty metal 🤟
Fluorine fires have entered the chat.
Oh shit, someone call the fluorine fire department to save the chat!
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)
Yeah, that’s a big fat nope from me 😬

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.
🤘
Pretty sure that’s the emoji for “thwip”.

I’m confused, that’s just a normal periodic table.
what? no, a normal periodic table has oxygen and carbon too!
Found the organic chemist
i mean, i think most chemists are organic
few are free range though
Found the astronomer.
Plutonium is not a real element.
It’s a dwarf element.
Plutonium can be on the periodic table but we do not grant it the rank of element.
Do you know what happens to hydrogen when the temp drops below 14K?
Yeah. Metal.
🤘
Metallic hydrogen may also make up parts of Jupiter’s core.
That’s fucking badass
Metallic or solid? Those are two different things, and depending on the answer, i will be going down a knowledge rabbit hole
Metals are crystal lattices with delocalized electrons.
That’s hard af
Doesn’t it also need to be under immense pressure? I don’t think low temperature alone is enough.
Yeah, I think that may be the case.
Should also have iron on there too
