No, ozone is not conductive. It is a dimagentic molecule.
No, fire is not conductive.
Yes, glycol is conductive.
Yes, iron is conductive.
No, magnets are not conductive. Magnets do not allow electricity to flow through them like conductive materials do.
Yes, osmium is a metal and is conductive.
No, ethylene glycol is not conductive.
No, spider webs are not conductive.
Yes, diamonds are not conductive of electricity.
No, Scotch tape is not conductive.
Lightning is a massive flow of electrons, that superheats gas to a conductive plasma state, and radiates broad spectrum energetic radiation... including ionizing radiation. Either the oxygen atoms in the plasma, or the ionizing radiation breaks apart oxygen molecules to make oxygen atoms, then some of these now-loose oxygen atoms combine with oxygen molecules to make ozone.
yes, it is a strong electrolyte (very conductive)
Metals and metalloids are conductive.
