Is every element crystaline?

[H2SO4]

I have a periodic table that shows the crystal structure of all the elements. I knew metals had crystal structures, but i didnt know that oxygen was crystaline and same with helium. Are they just saying that the altropes of these elements are crystaline (like sulfur and phosporus).

[Ophiolite]

No. If the temperature of any material is lowered sufficiently it will form a crystalline solid. Helium has the lowest melting point of all elements - less than a degree above absolute zero.

Helium, most stable of all elements.

Have they even solidified Helium yet?

[budullewraagh]

yes. it has magnetic properties, supposedly

[coquina]

yes. it has magnetic properties, supposedly

 

Isn't it about time to swap that hat for bunny ears?

[budullewraagh]

dr lang likes being santa. he'll take it off sometime soon

[H2SO4]

I guess at decreased pressures they could solidify helium, i don't see why not.

[budullewraagh]

at increased pressures, actually, they have

[jdurg]

Yeah, I think Helium is one of the only elements that cannot exist as a solid at atmospheric pressure.

[budullewraagh]

i think it can be, but it just needs to be ever so slightly above absolute zero

[H2SO4]

Ya, i meant at elevated pressusers

 

 

Can superfluidity occur in other element than helium?

[BenSon]

I dont think so all other elements solidify at too high temperatures.

We don't usually try to solidify gases such as Nitrogen without increasing pressure. And helium is the only gas I know of that shows superfluidity near 0K. Any researchers there knows?
