In summary, the conversation discusses the possibility of creating plasma in the regular atmosphere by ionizing atoms, specifically hydrogen. It is mentioned that gaseous hydrogen is not in the form of atoms in the atmosphere and that it is possible to create plasma in the atmosphere by generating high enough voltages. The required voltage for ionization is approximately three million volts per metre, which can be achieved with a single volt if the gap is thin enough. A helpful tutorial on creating static sparks is also provided.

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?

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.

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.

So how many volts will it take to ionize air.

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

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

FAQ: Is it possible: ionizing atoms in free-air

Can atoms be ionized in free-air?

Yes, it is possible to ionize atoms in free-air. Ionization is the process of adding or removing electrons from an atom, resulting in an electrically charged particle. This can occur in any environment, including free-air, as long as there is enough energy to overcome the binding energy of the electrons in the atom.

How is ionization of atoms in free-air achieved?

Ionization in free-air can be achieved in several ways, including through exposure to high levels of radiation, collisions with high-speed particles, or intense electric fields. These processes provide the necessary energy to remove electrons from atoms, resulting in ionization.

What are the applications of ionizing atoms in free-air?

The ability to ionize atoms in free-air has many practical applications, including in medical treatments such as radiation therapy for cancer, in air purification systems, and in the production of electronic devices and materials. It also plays a crucial role in understanding and studying the properties of matter.

Are there any potential dangers associated with ionizing atoms in free-air?

Yes, there are potential dangers associated with ionizing atoms in free-air. High levels of ionizing radiation can be harmful to living organisms, and precautions must be taken when working with such environments. Additionally, the use of ionizing radiation in medical treatments must be carefully controlled to minimize any potential risks to patients.

Can ionizing atoms in free-air be used for energy production?

Yes, ionizing atoms in free-air can be used for energy production. This is the principle behind nuclear power plants, where atoms are split apart through a process called nuclear fission, resulting in the release of large amounts of energy. However, this process also has potential risks and must be carefully managed and controlled.
