To get helium you can use fractional distillation of liquid air.
-or-
If you just wanted to separate helium from a MIXTURE of helium and argon you could use diffusion. Since helium is lighter than air while argon is heaver than air. You can capture the helium as it "diffuses" away from argon.
The solubility of argon in water is very low: 0,0537 V/V. By heating argon is easily released and water vapours are fast condensed.
One posibility is to reduce the temperature of the mix to -225oC. The argon will freeze into a solid at approximately -190o while the helium will remain gaseous until -272o.
hydrogen or heliumhydrogen or helium
Argon and Helium are part of the noble gasses family.
argon
No, helium argon and radon are members of the noble gas family.
helium, neon, argon, krypton, xenon and radon
hydrogen or heliumhydrogen or helium
Argon and Helium are part of the noble gasses family.
noble gases
No. Both helium and argon are chemically inert.
argon
They form a mixture of argon and helium. Both argon and helium are noble gasses, meaning that the do not usually react and certainly will not react with one another.
It makes a helium-argon mixture - nothing more, nothing less.
They are gases.
No, helium argon and radon are members of the noble gas family.
helium, neon, argon, krypton, xenon and radon
Helium, neon, and argon are the three lightest members of the noble gases.
Argon has a higher mass number which means it has more particles in its nucleus than helium so I would go with argon.
