He~2~
Does that decay into SHeMoNa?
Edit. Corrected my bad mixed up spelling
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.
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.
Plutonium is not a real element.
Plutonium can be on the periodic table but we do not grant it the rank of element.
It's a dwarf element.
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."
I'm confused, that's just a normal periodic table.
Found the astronomer.
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
What about metallic hydrogen in the core of planets?
"Wait, they're ALL metals?"
"Always have been."
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.
