Is it possible: ionizing atoms in free-air

[Kalrag]

Alright here's a question for everyone that has some input. Can we ionize atoms, say hydrogen, in free air? This is hard to explain, but can we make plasma in the regular atmosphere? Thats the only way I can word it. So is it possible?

 

[Borek]

Gaseous hydrogen is not in the form of atoms, it is in diatomic molecules.

There is almost no hydrogen in atmosphere.

Finally - yes, it is possible to make plasma in atmosphere. You have seen it many times.

 

[ACPower]

Top physicists are able to create high enough voltages to ionize air simply by padding around in their socks on the carpet in the dry winter air, then touching a grounded conductor.

 

[Kalrag]

So how many volts will it take to ionize air.

 

[Dadface]

So how many volts will it take to ionize air.

An electric field strength of about three million volts per metre.

 

[Borek]

Which means single volts will be sufficient if the gap is thin enough.
