everything else other than hydrogen is a metal

>>2277535
Of course it is, silly.

No you idiots, hydrogen is not a metal, it's a super metal. It burns with the brightness of a billions and billions of suns and doesn't afraid of anything.

>>2277535
Condensed hydrogen acts as a metal, but hydrogen tends to react as a non-metal.

Why do we call some elements metals anyway? I never gave it a thought.

>>2277558
I'd assume because they're solid at room temperatures and are (usually) reflective?
Correct me if I'm wrong.

Has to do with its conductivity. I.e. the configuration of valence electrons when you have a block of metal isn't localized to each atom/bond, they are floating freely in a "sea of electrons". At least in the most simplistic sense.

>hydrogen
AND helium, I think

>>2277558
Certain physical and chemical properties are common among metals, such as malleability, ductility, sheen, and the tendency for electrons to form a lattice.

>>2277559
A metal is lustrous, a good conductor of heat and electricity, mailable, and ductile.

>>2277563
no helium is very hard to get to a solid stage to test its conductivity but it is classed as a not metal for various reasons

>>2277582
That's what I meant, helium and hydrogen aren't metals, every other element is... Sigh... I was referring to >>2277539
It was kinda trolling, but it's actually an astrophysicsfags inside joke. In astrophy. everything except H an He is called a metal.

>>2277654
well some astrophysicists define metal as after helium some after carbon it depends who you ask

Search thread for band gap.
Zero results.

good question. I'm a chemfag, and I would say yes because of it's placement on the periodic table, despite the fact that it doesn't exactly exhibit most properties seen with most metals. it has to do with valence electrons and electronic configuration more than anything. I'm glad so many people know this. also, >>2277549

Actually metallic character is defined by how well the substance is oxidized. Since hydrogen can be oxidized fairly easily, it's a metal. But its 1s orbital can make it both metallic or nonmetallic.

AU called. He's pissed at you spreading your vile lies.

>>2277673

Lies!!! Filthy lies and crapspackle...

>>2277565

This man is corrent.

Hydrogen is only where it is on the period table to show where it's charge is, sometimes it's put next to helium as a halogen, but really it's just kind of it's own thing that's hard to define. IT HAS ABSOLUTELY NO METALLIC CHARACTER OR PROPERTIES. Please go take basic chemistry and stop failing at life.

Wanna know how to make room-temperature metallic hydrogen?

>>2277766

What about solid hydrogen at cryogenic temperatures?

>>2277766
>IT HAS ABSOLUTELY NO METALLIC CHARACTER OR PROPERTIES.
mfw liquid hydrogen displays electronic character identical to that of bulk metals

Actually, Hydrogen can become a metal, under enough pressure. The interiors of all of the gas giant planets may be made out of it.

>>2277766

Wrong.

Hydrogen is where it is on the table to show how it bonds with other elements.

Ther periodic table is in no way organized by each elements state in anyway. If it is put anywhere else that table is wrong.

>>2277535
It can be. It might even be superconducting at room temperature. It might even be like dry ice(if it is, it will make a great rocket/car fuel).

Well, Hydrogen is on the RIGHT side of the "elemental staircase" so it IS considered a "non-metal" at room temperature. However many elements can act in very different ways under certain conditions (such as extreme coldness or extreme heat).
