I am trying to understand what happens inside various types of air ionisers.
Some of them are sold for their purported health effects (which I do not want to discuss here), another type are used in industry to control electrostatic charges on surface of materials. Also there are some natural processes where oxygen form is modified by electric current namely thunderstorms.
Can an oxygen molecule be broken by placing it into a strong external electric field?
If yes how is it possible because as we know the oxygen atoms in molecules are bonded by a non-polar bond?
What are possible by products of this process (even temporary one)?
I assume that air is composed only from oxygen (no nitrogen, argon, carbon dioxide etc.).
